Silicon carbide reinforced metal oxide composite material and preparation method thereof
The invention relates to the technical field of nuclear structural materials, and particularly discloses a silicon carbide reinforced metal oxide composite material and a preparation method thereof. The material comprises the following components in parts by weight: 2-8 parts of modified whiskers, 5-8 parts of tungsten-molybdenum mixed powder and 80-98 parts of zirconium oxide-aluminum oxide mixed powder, the modified crystal whiskers are obtained by mixing silicon carbide crystal whiskers and boron nitride crystal whiskers according to a weight ratio of 1: (0.2-0.8) and then treating the silicon carbide crystal whiskers and the boron nitride crystal whiskers with an amino reagent. The bending strength and the fracture toughness of the material are remarkably improved.
本申请涉及核用结构材料的技术领域，具体公开了一种碳化硅增强金属氧化物复合材料及其制备方法。所述材料包括以下重量份的组分：改性晶须2‑8份，钨钼混合粉末5‑8份，氧化锆‑氧化铝混合粉末80‑98份；所述改性晶须是将重量比为1:(0.2‑0.8)的碳化硅晶须和氮化硼晶须混合后，经包括以氨基试剂处理的步骤得到。该材料的弯曲强度和断裂韧性显著提高。
