Calcining a alumina thermal conduction polishing hot spraying high temperature resistance
Product name: high temperature calcination T series
Overview:Using tunnel kiln, low-sodium ceramic alumina can be calcined to ceramic products of α Crystalline phase at temperature of 1450℃ -1520 ℃.It has excellent characteristics of chemical stability, resistivity, heat resistance, thermal conductivity, hardness and mechanical strength, high sintering performance and stable shrinkage
Application area:
electronic ceramic (spark plug, electronic vacuum tube, substrates) wear-resistant ceramics, fine ceramics, high-level refractory materials etc..
