摘要
研究了石英陶瓷坩埚废料的组成及物相特征,并用该废料配制首饰铸粉进行了黄铜首饰铸造试验。结果表明,石英陶瓷坩埚废料的主晶相为方石英,纯度超过99.8%,用其制备的方石英粉添加到铸粉中可以有效补偿石膏失水引起的收缩,保证铸造饰品的精度和表面质量,是一种较为理想的铸粉原料。
The material constitution and the phase characteristic of fused silica ceramic crucible waste were studied, and the brass jewelry casting experiments were conducted taking the waste as investment powder. The results show that the main crystalline phase of fused silica ceramic crucible waste is cristobalite and its purity is more than 99.8%. Adding the cristobalite powder made from the waste into the investment powder can effectively compensate the contraction induced by gypsum dehydration, and ensure the casting jewelry precision and surface quality. So it is an ideal imvestment powder raw materials.
