Technical Ceramic

 

Classification of Technical Ceramic:

1. Oxide ceramic
   Most of the oxide ceramics have a melting point above 2000 °C. The firing temperature is about 1800 °C. They possess a single-phase polycrystalline structure, sometimes with a small amount of gas phase.
   (1) Alumina (corundum) ceramic
   The structure is O2- arrange in a dense hexagonal structure. Alumina is one of the most commonly used, and depending on the amount of impurities it contains, it can be red (like ruby) or blue (like sapphire).

(2) Zirconia ceramic
The melting point of zirconia ceramics is above 2700 °C. It resists high temperatures up to 2300 °C. The recommended use temperature is 2000 °C~2200 °C. These are ideal technical ceramics for applications demanding high resistance.

2.Carbide ceramic

(1) Silicon carbide ceramics are a type of technical ceramics used for their hardness and wear resistance.

(2) Boron carbide

(3) Other carbide

3.Nitride ceramics

(1) Silicon nitride ceramic

(2) Boron nitride ceramic
