Guide To The Modern Use Of Ceramics

by

Amit Kheterpal

Ceramics as a material were initially used by the scientists in the space industry. They used the ceramic sheets on the outside to create a heat shield against the high temperatures which were generated when the shuttles were entering the earths atmosphere.

Once the ceramics as material was popular its first use was in the ball bearings industry where they used the ceramic material to make ball bearings which were being used wherever there were high intense heat situations.

Now the ceramic industry is a large industry with the ceramics being used in every conceivable form ranging form the flooring industry where ceramic tiles are popular to the high end aerospace industry.

Initially the ceramics were the refractory material which is still used in the flooring industry but for the high end uses there were hybrids developed like the silica carbide and the silica nitride. These ceramics have advantages over the traditional steel or other materials.

Ceramics are corrosion resistant as well as they are heat resistant and of course they much better at bearing heavier loads than steel. It is for this specific reason that the ceramics have been used by the industry even in the medicine world. Specific for bone implants and orthopedic restorations the ceramic material is used as it is very hard and tough to sustain pressures.

The other major use of ceramics is now being done in the semiconductors world. The integrated chip circuits that are used computers and other high techs gadgets have ceramic material. The ceramic material is also used in manufacturing of insulators and capacitors.

That said the future seems to be very bright for ceramics and a lot of research is being done to leverage the strength and the corrosion resistance of the ceramic materials.

In fact one of the major uses of ceramic has been in the cosmetic dentistry industry especially the porcelain veneers. Porcelain veneers are used by the cosmetic dentists makes new veneers for use on their patients. Porcelain veneers have a vitreous and glassy feel and that is why the look good on the tooth for a glassy white finish as dental crowns.

Ceramics as material is been continually evolved to make sure that in nowadays world it is environment friendly and can be easily disposed off also. These materials are hard and hence pose challenges when they are recycled as they cannot break down easily. So there is more research being done nowadays to look into this aspect of the ceramics.

Perhaps you have keyed the mic on your VHF in order to initiate a radio examine and wondered if any person actually heard you? I’ve. Radio transmission issues trouble just about every single boater at one particular time or one more despite the fact that today’s VHF radios would be the most durable, dependable and also cost-effective marine electronics on the market. You can find, even so, a handful of wise practice things you’ll be able to do to maximize your radio’s wedding party and ensure that fellow boating fanatics, Sea Tow or the You.S. Coast Guard will certainly hear your calls.

In order to insure that others notice me loud and clear when it is really time to share the productive fishing spot or check in using a buddy motorboat when out for a saturday and sunday cruise, I commonly buy the best antenna that I can afford. The particular heavy-duty Shakespeare Galaxy eight-footer is my favorite 6-dB antenna and it’s priced just right (below $150). Its heavy-duty radome (fiberglass tube), resilient chrome-plated brass mounting connection, along with the beefed-up wiring array on this antenna have always enabled me personally to fit out the full 25-watts regarding output power on my personal MarCeeJay’s VHF transmissions.

Most fiberglass antennas needs to be exchanged each four to five many years, but frequent navigation throughout rough waters can cut short that time frame. Regardless of whether it is really these Shakespeare or a competitor’s model, an aerial exposed to extreme conditions will build up cracks in its body after a while because of UV rays along with the tough saltwater environment. Be confident to perform periodic inspections of your aerial to watch for troubles due to extreme use.

Stay absent from bargain basement $29 antennas that electronics vendors bundle with their VHF radios. They’ll not give you the range or longevity you anticipate from your critical communications website link.

Nevertheless an additional prospective difficulty location with VHF transmission and wedding party issues may be a function from the often-quirky PL-259 male connection at the stop of the antenna cable television. I check mine at least two or 3 periods a season for corrosion or loose wiring internet connections since these troubles can significantly compromise your VHF communications, both in transmitting and receiving modalities. When it really is time to replace the connection, I use Shakespeare’s fast transform PL-259 package. It’s readily available for underneath $10 for the most part marine stores.

Following I renovated a classic 27-foot Phoenix sportfisher a few decades back again, I experienced a widespread communications issue. My VHF had a vulnerable overall transmit sign together with particularly poor reception associated with inbound VHF messages. I contacted Don Henry, director of Shakespeare’s Marine Products Group, to help solve the issue. Don surmised that this bundling of my extra-long VHF aerial wire in proximity for you to my Loran, GPS and DGPS antenna cables may be causing disturbance and that there might also be a short within the circuitry of our multiple VHF antenna wire contacts (I had an extension cable connected).

The three-fold solution to solving this issue was to raise the antenna over the hardtop in order to get a lot more elevation and, therefore, a bit much more attain in its transmit and obtain range. He also proposed that I rewire my radio stations having a single piece of cajole cable tv and install it away from the prospective EMF interference of the some other antenna wires and customize the connection to my Uniden VHF using a new solderless Shakespeare PL-259 connect.

A Shakespeare Galaxy 5228-4 heavy-duty extension pole added four feet in order to my new, eight-foot Galaxy 5225-XT antenna, which was mounted around the starboard aspect of my Phoenix’s cuddy cabin and also braced which has a standoff support bracket connected to the hardtop. The antenna wire ended up being snaked to my VHF separate via other navigation equipment aerial cables, along with the circuit relating to the cable and VHF was carried out with Shakespeare’s new crimp-on connectors.

As a ultimate and quite essential action, My spouse and i employed one particular of Shakespeare’s inexpensive (beneath $50) ART-1 antenna/radio testers to test the signal and its connections. This check allowed me to confirm how the radio was pumping away its maximum 25-watts of power. It also indicated there was minimum sign loss on reception – I could be noticed loud and clear — and there were no shorts within the PL-259 connection or the aerial connection.

Shakespeare also offers a extra superior ART-3 tool having a couple of far more features like but either trialist will do the job and is more advanced than performing radio checks each hour to create certain your VHF is actually performing up to expectations.

Add Henry’s advice helped me improve our VHF radio’s reception and I can now speak with anglers who are 20 or even more miles away from me. The actual ART-1 and ART-3 devices are outstanding issue solvers and their three-phase analysis must assist you to to quickly pinpoint any kind of issues in your VHF/antenna circuit. To utilize either unit, merely plug the PL-259 connection from your antenna into a person aspect, then affix the unit’s coax wire into the other, and then connect the opposite stop in the quick cable tv into your radio’s antenna input. Follow the step-by-step instructions supplied with each and every unit and you must have got real communications peace of mind quickly.
