用于微波加热的陶瓷基透波承载体及生产方法
摘要：
本发明涉及一种用于微波加热的陶瓷基透波承载体及生产方法，本发明的陶瓷基透波材料成分组成的表达式为xMeO·yAl2O3·zSiO2，其中Me为镁或钇，各成分的具体含量为2重量％≤x≤8重量％，35重量％≤y≤45重量％，50重量％≤z≤60重量％，x+y+z＝100％，配入材料总重量5-8％的粘结剂，制胚成型后烧结。该材料的介电常数为6-10，具有很好的微波穿透性能；其在20-1000℃热膨胀系数为2-3×10-6/℃，具有极小的加热膨胀率和优异的抗热震性能；同时其荷重软化温度≥1600℃，能满足微波高温合成、烧结、煅烧及热处理等工艺要求；承载体能够适应大尺寸管、板、砖、匣钵、坩埚和异型件等的加工要求。
摘要（英）：

This invention relates to a ceramic-based wave-permeable loading body used in micro-wave heating conditions. The components of this invention products have the representation of: xMeO.yAl2O3.zSiO2, wherein Me=magnesium or yttrium, and the specific (weight percentages) of the components: 2%<=x<=8; 35%<=y<=45%; 50%<=z<=60%, and x+y+z=100%. After that, it is added with adhering agent of 5-8% of the total raw materials above-mentioned, and making blanks and being sintered to obtain final products. This inventive products have advantages of: dielectric constant=6-10, very low expansibility during heating, excellent thermal shock-resistance, its softening point during loading>=1600deg.C, can be used for making tubes, plates, bricks and crucibles.
