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..
