Silicon carbide ceramic product, preparation method thereof and silicon carbide ceramic crucible side
The invention belongs to the technical field of ceramic materials, and provides a silicon carbide ceramic product, a preparation method thereof and a silicon carbide ceramic crucible side. The method comprises the following steps: injecting a mixture into a mold, pressing, and demolding to obtain a green body; sequentially carrying out low-temperature drying and high-temperature drying on the obtained green body to obtain a dried green body; under a vacuum condition, carbonizing the obtained dry green body to obtain a carbonized green body; and scattering silicon powder to the hollow position of the carbonized green body, and sintering under a vacuum condition to obtain a silicon carbide ceramic product. The silicon carbide ceramic product can be a silicon carbide ceramic crucible side. The silicon carbide ceramic crucible upper prepared by the invention does not react with silicon steam during use, and has better oxidation resistance, and the service life of the silicon upper can be greatly prolonged.
本发明属于陶瓷材料技术领域，提供一种碳化硅陶瓷产品及其制备方法和一种碳化硅陶瓷埚帮。本发明将混合料注入模具后进行压制，脱模得到坯体；将所得坯体顺次进行低温干燥和高温干燥，得到干燥坯体；在真空条件下，将所得干燥坯体进行碳化，得到碳化坯体；向所得碳化坯体的中空位置撒上硅粉后，在真空条件下进行烧结，得到碳化硅陶瓷产品。所述碳化硅陶瓷产品可以为碳化硅陶瓷埚帮。本发明制备的碳化硅陶瓷埚帮在使用时不与硅蒸汽发生反应，同时具有较好的抗氧化性，可大幅度提升硅帮的使用寿命。
