Alumina ceramic materials can be processed to produce many ceramic parts, such as ceramic shaft, ceramic rod, ceramic tube and so on. Today, Kezhong Ceramic Factory will introduce to you the new discovery of the advantages of alumina ceramic parts processed.
Alumina ceramic shaft, alumina ceramic shaft is also called wear-resistant alumina ceramic lining shaft. Alumina ceramic shaft is mainly made of alumina as raw material, rare metal oxide as solvent, calcined at 1700℃.
Alumina ceramic shaft has high impact toughness, wear resistance, corrosion resistance, impact resistance, heat resistance, rich and colorful raw materials, cheap price, commodity environmental protection and zero pollution.
The key chemicals that make up alumina ceramics are steel jade, laminated glass phase and air vent. If the temperature is too high in the whole process of calcination, or in the case of heat insulation and heat preservation, the time is too long, then it will not only the production of crystallization, but also improve its phasor. Thus reducing the strength and hardness of alumina ceramics.
In fact, how much is the composition of aluminum oxide, for the wear resistance of raw materials is no immediate harm, the wear resistance of raw materials, the ultimate influencing factor is its phase composition, and its microstructure. Therefore, if we want to get alumina ceramics with high wear resistance, we should not only fully consider the relative density level, bending and pressure resistance, but also think of ways to improve its hardness, as well as its toughness at the time of fracture.
Alumina is an ionic crystal with stable structure. It still insulates well when used at high frequencies, high pressures and high temperatures, and its loss and dielectric constant are not large. It is widely used in electronics industry, used in solid extruded electrical subgrade board socket, shell, porcelain frame and miniature glass window, missile radar antenna protective cover, etc.
Alumina ceramic thermal insulation materials are widely used in a variety of high temperature furnace body and rotary kiln, both heat and heat insulation.
