摘要
研究了原料粉末对碳化硼陶瓷常压烧结性能的影响.试验表明增加原料粉末的比表面积和纯度能显著地促进烧结过程,且提高其烧结的质量密度.当比表面积大于16m2/g时,可使烧结体的相对密度达到98.7％以上,抗弯强度达到456 MPa,硬度HV达到为2790.制品的性能接近热压制品的水平.
The effect of raw material powder on the sintered properties of Boron Carbide was investigated. The results indicate the sinterability was greatly improved by increasing the BET and purity of raw material powder, the density of articles was correspondingly increased markedly. When the BET of the raw material powder is 16m2/g, the sintered body reached the relative density of 98.7%, the bending strength of 456 MPa, and the Vicker hardness of HV2790, which approached those of hot-pressed product.
