Method for preparing boron carbide ceramic material by using crystalline silicon cutting waste as additive
The invention belongs to the technical field of comprehensive utilization of secondary resources and material synthesis, and particularly relates to a method for preparing a boron carbide ceramic material by taking crystalline silicon cutting waste as an auxiliary agent. In order to overcome the defects in the prior art, according to the advantages of fine granularity and high body purity of the crystalline silicon cutting waste, the crystalline silicon cutting waste is used for preparing the B4C ceramic. Meanwhile, aiming at the problems that the crystalline silicon cutting waste has an oxidation film and is difficult to uniformly disperse, the invention provides acid pickling deoxidization, graded heat preservation, graded material mixing and other solutions. According to the method, secondary comprehensive utilization of waste resources is achieved, waste is turned into wealth, the economic value is high, the process is simple and feasible, economical efficiency is good, industrial production is easy to achieve, the obtained boron carbide ceramic has high density and good comprehensive mechanical performance, and the hardness improving effect is obvious.
本发明属于二次资源综合利用与材料合成技术领域，具体涉及到一种以晶体硅切割废料为助剂制备碳化硼陶瓷材料的方法。针对现有技术的不足，本发明根据晶体硅切割废料粒度细、本体纯度高的优点，提出了将晶体硅切割废料用于B4C陶瓷的制备。同时针对晶体硅切割废料存在的氧化膜及难均匀分散的问题，提出了酸洗除氧、分级保温、分级混料等解决方法。本发明实现了废弃资源的二次综合利用，变废为宝，经济价值高，工艺简单可行，经济性好，易于实现工业化生产，所得碳化硼陶瓷具有较高的致密度和良好的综合力学性能，硬度提升效果明显。
