产物先容 产物参数

氮化铝陶瓷是共价键化合物,属于六方晶系,纤锌矿型的晶体布局,呈红色或灰红色。氮化铝导热性好,热收缩系数小,是杰出的耐热打击资料。具备杰出的抗热震性。AlN的导热率是Al2O3的2~3倍,热压时强度比Al2O3还高。氮化铝陶瓷片对Al和其余熔融金属、砷化镓等具备杰出的耐蚀性,特别对熔融Al液具备极好的耐侵蚀性,还具备杰出的电绝缘性和介电性子。但氮化铝的低温抗氧化性差,在大气中易吸潮、水解,和湿氛围、水或含水液体打仗发生热和氮并敏捷分化。在2516℃分化,热硬度很高,即便在分化温度前也不硬化变形。氮化铝和水在室温下也能迟缓地停止反映,而被水解。和枯燥氧气在800℃以上停止反映。
