Crucible coating as well as preparation method and application thereof
The invention provides a crucible coating as well as a preparation method and application thereof, and particularly relates to the technical field of crucible coatings. The crucible coating comprises a first coating and a second coating, the first coating comprises graphite powder, silicon nitride and silica sol, and the mass ratio of the graphite powder to the silicon nitride to the silica sol is (5-7): (1-2): (20-25); the second coating comprises first quartz powder, second quartz powder, silicon nitride and silica sol, and the mass ratio of the first quartz powder to the second quartz powder to the silicon nitride to the silica sol is (5-8): (0.7-1): (3-5): (20-25); the first coating and the second coating are sequentially arranged on the outer wall of the crucible from inside to outside. According to the crucible coating, the service life of the crucible can be greatly prolonged, the oxidation rate is improved, and the production cost is reduced.
本发明提供一种坩埚涂层及其制备方法和应用，具体涉及坩埚涂层技术领域。所述坩埚涂层包括第一涂层和第二涂层，所述第一涂层包括石墨粉、氮化硅和硅溶胶，所述石墨粉、氮化硅和硅溶胶的质量比为(5～7):(1～2):(20～25)；所述第二涂层包括第一石英粉、第二石英粉、氮化硅和硅溶胶，所述第一石英粉、第二石英粉、氮化硅和硅溶胶的质量比为(5～8):(0.7～1):(3～5):(20～25)；所述第一涂层和所述第二涂层由内至外依次设置在坩埚的外壁上。本发明的坩埚涂层可以大幅度提升坩埚的使用寿命，改善氧化速率，降低生产成本。
