Alumina Ceramics:
Temperature range of the tendency of alumina ceramics to transform into inclined pyroxene or refractory pyroxene at 1042 ° C. Properly increasing the cooling rate can reduce this tendency of crystal-plastic conversion, avoid glass phase crystallization, and fully utilize glass phase wrapping The effect of the original refractory and inhibiting the transformation of its Ceramic Plunger crystal form has a certain effect on preventing the aging of talc porcelain. Research and practice have shown that strict formula design and selection of raw materials and optimization of process conditions are important measures to prevent or avoid aging of talc porcelain. One of the prone quality problems of talc porcelain is cracking, which causes product scrap. This is often caused by the extrusion or molding of talc porcelain and improper processing of talc raw materials. The Alumina Zirconia talc raw material is anisotropic. When used directly in batching and molding, this talc powder tends to have smaller flakes. The directional arrangement is formed during molding, which results in the molding blanks also being individually anisotropic. When stress occurs during the firing process, cracks or cracks appear on the porcelain and become waste products. Although some cracks or cracks appear on some porcelain, the mechanical strength of the porcelain decreases due to the greater stress in the porcelain. Affects the actual use of porcelain. In order to prevent this kind of quality problem, the main measures taken in production are pre-calcining the talc raw material to destroy the layered structure of the talc raw material. Then it is ground. The talc raw material with granular structure is used in the production of talc porcelain after grinding. The main crystalline phase is the original refractory ceramics, which uses talc as the main raw material, and Industrial Ceramic adds appropriate amounts of clay, bentonite and barium carbonate to high-temperature sintered ceramic materials. It has high strength and low dielectric loss. Used for high-frequency device parts, small-capacity high-power capacitors, and fine-tuned ceramic dielectric heaters.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
