The invention discloses a high-temperature-resistant crucible and a manufacturing process thereof, and particularly relates to the field of crucibles. Main materials of the crucible adopted include, by weight, 30-50 parts of quartz sand, 5-10 parts of bauxite, 10-30 parts of diatomite, 10-15 parts of dolomite, 20-40 parts of magnesite, 20-40 parts of titanium diboride powder, 30-50 parts of titanium carbide, 10-30 parts of zirconium diboride powder, 10-20 parts of aluminum-chromium slag and 10-20 parts of silicate. The whole process steps are reasonable, a binder prepared from the bauxite, themagnesite, the titanium diboride powder, the titanium carbide, the zirconium diboride powder, the aluminum-chromium slag and phenolic resin is adopted as a raw material, the raw material is integrated from the interior of the crucible by utilizing the chemical stability of the raw material, the stability of the crucible in a high-temperature state is effectively improved, and the phenomenon thatthe surface is broken after long-time use is avoided, so that the service lifetime is prolonged.
本发明公开一种耐高温坩埚及其制造工艺，具体涉及坩埚领域，一种耐高温坩埚，其中所使用的主料包括以下重量份数的原料：石英砂30‑50份、铝矾土5‑10份、硅藻土10‑30份、白云石10‑15份、菱镁矿20‑40份、二硼化钛粉末20‑40份、碳化钛30‑50份、二硼化锆粉末10‑30份、铝铬渣10‑20份、硅酸盐10‑20份。本发明整体工艺步骤合理，采用铝矾土、菱镁矿、二硼化钛粉末、碳化钛、二硼化锆粉末、铝铬渣以及酚醛树脂制作的粘结剂作为原料，利用原料本身的化学稳定性能，从坩埚内部对其进行整合，有效的提高了坩埚在高温状态下的稳定性，避免了长时间使用之后出现表面碎裂的现象，进而延长了起使用寿命。
