Connecting method of silicon carbide ceramics and connecting piece
The invention provides a silicon carbide ceramic connecting method and a connecting piece, and the connecting method comprises the following steps: cleaning the interface of a silicon carbide ceramic piece to be connected, and after cleaning, arranging a connecting material or slurry containing the connecting material at the interface of the silicon carbide ceramic piece to be connected, then combining and fixing the silicon carbide ceramic pieces to be connected to obtain prefabricated connecting pieces; wherein the connecting material comprises a silicon-carbon composite material; and sintering the prefabricated connecting piece, enabling the connecting material to react to form silicon carbide, and connecting silicon carbide ceramics to obtain the silicon carbide ceramic connecting piece. According to the connecting method, the problem that impurity elements and internal stress are introduced in an existing connecting method can be solved, so that the purity of the ceramic connecting piece can be guaranteed, and the situation that internal stress is gathered due to the difference of internal thermal expansion coefficients, and the ceramic piece is damaged is avoided.
本发明提供了一种碳化硅陶瓷的连接方法及连接件，所述连接方法包括如下步骤：对待连接的碳化硅陶瓷件界面进行清洁，所述清洁后，在待连接的碳化硅陶瓷件界面处，设置连接材料或含连接材料的浆料，然后将待连接的碳化硅陶瓷件进行组合和固定，得到预制连接件；其中，所述连接材料包括硅碳复合材料；将所述预制连接件进行烧结，使所述连接材料反应形成碳化硅，将碳化硅陶瓷连接，得到碳化硅陶瓷连接件。本发明所述连接方法能够避免现有连接方法引入杂质元素和内应力的问题，从而能够保证陶瓷连接件的纯度，并避免因内部热膨胀系数的差异而引起的内应力集聚，造成陶瓷件损坏的情况。
