Mobile phone rear cover material and preparation method thereof
The invention relates to a mobile phone rear cover material and a preparation method thereof. The mobile phone rear cover material is formed by compounding graphite micro-particles, potassium niobateand zirconium oxide, wherein the graphite microparticles can be uniformly dispersed in the potassium niobate composite zirconium oxide ceramic mobile phone rear cover material through a melting method, the KNbO3 synthesis raw materials are K2CO3 and Nb2O5, and bismuth oxide is added in the calcination process of the KNbO3 synthesis raw materials and a zirconium oxide raw material. The KNbO3 synthetic raw material and the zirconium oxide raw material are subjected to composite calcination, so that a uniform fine-grain structure is shown, and meanwhile, the KNbO3 synthetic raw material also hasthe characteristics of very high Curie temperature (about 420 DEG C), high frequency constant and the like. Due to no lead, the pollution to the environment can be reduced, and the volatilization of potassium and sodium in the sintering process can be avoided or reduced through hot-pressing sintering, so that a compact product is obtained. The preparation method disclosed by the invention is simple and convenient to operate and has an extremely wide application prospect.
本发明涉及一种手机后盖材料及其制备方法，所述手机后盖材料由石墨微颗粒、铌酸钾、氧化锆复合而成，石墨微颗粒通过熔融法可以均匀分散在铌酸钾复合氧化锆陶瓷手机后盖材料中，所述KNbO3合成原料为：K2CO3、Nb2O5，所述KNbO3合成原料通过与氧化锆原料煅烧过程中加入氧化铋。KNbO3合成原料通过与氧化锆原料复合煅烧，显现出均匀的细晶结构，同时还具有很高的居里温度(420℃左右)以及高的频率常数等特性。由于无铅、可减少对环境的污染，热压烧结，可避免或减少钾、钠在烧结过程的挥发，从而获得致密制品。本发明制备方法简单便于操作，具有极广阔的应用前景。
