Description

99.8 ALUMINA CERAMIC BLOCK STOCK RECTANGULAR BAR 3.612" x 1.200" x 0.460"
No.: 418
You are buying  ONE (1) only of a High Purity Alumina Ceramic Block Stock Bar Rectangular. It measures 3.612" x 1.20" x 0.460" thick. It is in excellent NEW condition.. They are made from 99.8% high purity Aluminum Oxide (Al2O3) which of course is Alumina. Generally the balance of composition for this purity Alumina material is of Silicon Dioxide (SiO2) which is Silica. This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature. They may be used for a variety of electrical, mechanical, and thermal applications. They are great for firing sample in a high temperature kiln. The may be slumped at 3100 F (1700 C). They are sufficiently thin to use as diffusers of light. The are great for both electronic substrates or sculptural works of art. They may also be used for jewelry or for applications requiring high wear or abrasion resistance. 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.
