Preparation method of reaction-sintered silicon carbide
The invention discloses a preparation method of reaction-sintered silicon carbide. The preparation method comprises the following steps: preparing silicon particles; adding the obtained silicon particles and carbon powder into an organic binder, and uniformly mixing and stirring the mixture to obtain a mixture; and putting the mixture above a silicon carbide biscuit, and carrying out a reaction ata high temperature to obtain the reaction sintered silicon carbide. According to the preparation method of the reaction-sintered silicon carbide, silicon particles are adopted to replace silicon powder, compared with a traditional preparation process, the pressing procedure is omitted, the preparation time is saved, the production efficiency and the effective space utilization rate are improved,the production cost is reduced; by adopting the preparation method, waste residues obtained after environment-friendly treatment are almost zero, and the environment-friendly effect is good .
本发明公开了一种反应烧结碳化硅的制备方法，包括以下步骤：制备硅粒；将所得硅粒、碳粉、加入有机粘结剂中混合搅拌均匀，得混合料；将混合料放于碳化硅素坯的上方，在高温下反应得所述反应烧结碳化硅。本发明所述一种反应烧结碳化硅的制备方法，采用硅粒代替硅粉，与传统的制备工艺相比省去了压制工序，节省了制备时间、提高了生产效率及有效空间利用率，降低了生产成本，且采用本发明所述的制备方法，环保处理后的废渣几乎为零，比较环保。
