This material is an extremely lightweight material with low thermal expansion and excellent strength, rigidity and thermal shock resistance; and has very good corrosion resistance to chemicals at high temperature, and high use temperature. It may be used for a variety of electrical, mechanical, and thermal applications. Because it has such very low thermal conductivity as most ceramic materials go, it might be used as platen for soldering jewelry or a as setter plate for firing parts in a kiln. The plate may also be used for high temperature dental and jewelry furnaces and as high temperature refractory turntables.
Your imagination is the only limiting factor in the spectrum of possible applications for this component. Be sure to view all photos as they are an integral component of the item description.
