Preparation method of silicon carbide slurry
The invention discloses a preparation method of silicon carbide slurry, and relates to the technical field of silicon carbide slurry preparation. The invention discloses a preparation method of silicon carbide slurry. The method comprises the following steps: S1, pretreating wastes: putting the collected wastes into an acid solution for soaking to remove metal and oxide impurities in the wastes, taking out the wastes from the acid solution. Silicon carbide powder is subjected to multiple times of acid pickling, and the pH value of silicon carbide slurry is adjusted, so the solid phase contentof the silicon carbide slurry can be greatly improved; ad in addition, a dispersing agent is added into the silicon carbide slurry, so that the dispersity and the uniformity of the silicon carbide slurry can be effectively improved, the quality of the produced silicon carbide ceramic is good, and the storage time of the silicon carbide slurry is long.
本发明公开了一种碳化硅浆料的制备方法，具体包括以下步骤：S1、废料预处理：将收集到的废料放入酸溶液中进行浸泡，去除废料中的金属和氧化物杂质，接着将废料从酸溶液中取出，本发明涉及碳化硅浆料制备技术领域。该碳化硅浆料的制备方法，通过S1、废料预处理：将收集到的废料放入酸溶液中进行浸泡，去除废料中的金属和氧化物杂质，接着将废料从酸溶液中取出，利用对碳化硅粉料进行多次酸洗，并且调节碳化硅浆料的pH值可以将碳化硅浆料的固相含量大大提升，降低碳化硅浆料的粘度，另外在碳化硅浆料中加入分散剂可以有效地提高碳化硅浆料的分散性和均匀性，使生产出来的碳化硅陶瓷质量更好，对碳化硅浆料的保存时间更久。
