Industrial ceramics (fine ceramics)

In fact, industrial ceramics is a general concept and belongs to a large category. Industrial ceramics can be divided into ordinary refractory ceramics, special ceramics (foreign known as fine ceramics) two categories. Refractory ceramics are mainly used in high temperature kilns, and are used as high temperature resistant supporting parts. The use and classification of special ceramics are more. In terms of color alone, common special ceramics (hereinafter referred to as ceramics) are pure white, pure black, gray, pink and blue, etc., although it is not colorful, but for people who first contact, it is also rich. If the texture of the wheel, the ceramic looks somewhat similar to ordinary marble, due to the use of high purity, ultra-fine ceramic powder after pressing, high temperature sintering. you can't see any pores or gaps with the naked eye, and if you want to use a slightly more technical word to describe it, I think "dense" is the right word. pick up a billiard ball size silicon nitride ceramic (a kind of fine industrial ceramics) ball weight is about 2 pounds, much heavier than ordinary billiard balls. Due to the high density of ceramics, the surface finish of the precision grinding ceramic sheet or ceramic ball can reach a mirror, which is a popular point that can shine a human shadow.
