ZTA ceramic material, heating element and preparation method thereof
The invention relates to a ZTA ceramic material, a heating element and a preparation method thereof. The ZTA ceramic material is formed by sintering a composition containing powder, and the powder isprepared from, by volume, 88%-96% of aluminum oxide powder and 4%-12% of zirconium oxide powder; the sintered aluminum oxide and zirconia have a grain size ratio of from 2.380 to 4.444. According to the ZTA ceramic material disclosed by the invention, the aluminum oxide and the zirconium oxide are taken as main materials, and the dosage ratio of the aluminum oxide to the zirconium oxide and the grain size ratio are adjusted, so that the effect of the zirconium oxide serving as a toughening phase is ensured, the problem of leakage current is avoided, and the use temperature of the ZTA ceramic heating material is increased.
本发明涉及一种ZTA陶瓷材料、发热元件及其制备方法，该ZTA陶瓷材料由包含粉体的组合物烧结而成，粉体由以下体积分数的组分组成：氧化铝粉88%至96%；氧化锆粉4%至12%；烧结后氧化铝和氧化锆的晶粒粒径比为2.380至4.444。本发明的ZTA陶瓷材料以氧化铝和氧化锆为主体材料，通过调整氧化铝和氧化锆的用量配比以及晶粒粒径之比，既保证了氧化锆作为增韧相的作用，又不至于产生漏电流的问题，提高了ZTA陶瓷加热材料的使用温度。
