High-density high-purity carbon ceramic crucible and preparation method thereof
The invention discloses a high-density and high-purity carbon ceramic crucible and a preparation method thereof, and the method comprises the following steps: carrying out vapor deposition on a carbon fiber crucible preform to obtain a carbon-carbon composite crucible; the carbon-carbon composite crucible is sequentially subjected to carbon densification treatment, cracking after organic gel dipping, purification and impurity removal, silicon carbide layer coating treatment and ceramization treatment, and the carbon-carbon composite crucible is obtained. The method disclosed by the invention has the characteristic of simplicity and convenience in operation, and the production efficiency of the carbon-ceramic crucible is remarkably improved. The carbon-ceramic crucible prepared by the method is high in density, high in purity, excellent in mechanical property, high in corrosion resistance and long in service life.
本发明公开了一种高密高纯碳陶坩埚及其制备方法，该方法是将碳纤维坩埚预制体采用气相沉积碳，得到碳碳复合坩埚；再将碳碳复合坩埚依次进行增密碳处理、有机凝胶浸渍后裂解、纯化除杂、涂碳化硅层处理和陶瓷化处理，即得。本发明的方法具有操作简便的特点，显著提高了碳陶坩埚的生产效率。通过该方法制备的碳陶坩埚密度高、纯度高，机械性能优异，耐腐蚀性能强，使用寿命长。
