The invention discloses a quartz ceramic crucible manufacturing method, which comprises: 1, preparing a quartz ceramic crucible green body: carrying out ball milling on quartz sand powder, and carrying out slip casting to obtain the quartz ceramic crucible green body; step 2, preparing a compact coating liquid: weighing the silicon nitride/niobium silicide coated microspheres, and uniformly mixing the silicon nitride/niobium silicide coated microspheres with silica sol to prepare the compact coating liquid; and step 3, preparing the quartz ceramic crucible: coating the compact coating liquid on the surface of a quartz ceramic crucible green body, and drying to obtain the quartz ceramic crucible. The particle size of the quartz sand powder is 50-100 microns, and the purity of the quartz sand powder is not less than 99.99%. The method for preparing the quartz ceramic crucible is simple and convenient in process, and the prepared quartz ceramic crucible has better usability.
本发明公开了一种石英陶瓷坩埚的制作方法，包括以下步骤：步骤1，制备石英陶瓷坩埚坯体：将石英砂粉末经过球磨后，以注浆成型的方式制备得到石英陶瓷坩埚坯体；步骤2，制备致密涂层液：称取氮化硅/硅化铌包覆微球与硅溶胶混合均匀，制备得到致密涂层液；步骤3，制备石英陶瓷坩埚：将致密涂层液涂覆于石英陶瓷坩埚坯体的表面，干燥处理后，得到石英陶瓷坩埚。石英砂粉末的粒径为50～100μm，纯度不小于99.99％。本发明制备石英陶瓷坩埚的方法工艺简便，制备得到的石英陶瓷坩埚具有更好的使用性。
