Magnesium fluoride composite ceramic and preparation method thereof
The invention relates to the field of neutron moderation, in particular to magnesium fluoride composite ceramic and a preparation method thereof, and the magnesium fluoride composite ceramic comprises a magnesium fluoride matrix, a binder and a sintering aid. Wherein the magnesium fluoride matrix accounts for 80wt%-95wt% of the total content of the composite ceramic; the addition amount of the binder is 0-1wt% of the total content of the composite ceramic; the addition amount of the sintering aid is 0-10 wt% of the total content of the composite ceramic; the sintering aid comprises at least one of lithium fluoride, calcium fluoride, aluminum fluoride and metal aluminum. According to the magnesium fluoride composite ceramic and the preparation method thereof provided by the embodiment of the invention, the probability of collision with neutrons is increased by increasing the fluorine concentration in the composite ceramic, so that the magnesium fluoride composite ceramic has a relatively good neutron moderation effect.
本申请涉及中子慢化领域，具体涉及一种氟化镁复合陶瓷及其制备方法，该氟化镁复合陶瓷包括氟化镁基体、粘结剂和助烧剂。其中，氟化镁基体占复合陶瓷总含量的80wt％～95wt％；粘结剂添加量为复合陶瓷总含量的0～1wt％；助烧剂添加量为复合陶瓷总含量的0～10wt％；助烧剂包括氟化锂、氟化钙、氟化铝、金属铝中的至少一种。本申请实施例提供的氟化镁复合陶瓷及其制备方法通过增加复合陶瓷内的氟浓度，增大了与中子发生碰撞的概率，从而具有比较好的中子慢化效果。
