Quartz fiber reinforced carbon-silicon dioxide composite material crucible and preparation method thereof
The invention relates to a quartz fiber reinforced carbon-silicon dioxide composite material crucible and a preparation method thereof, and belongs to the technical field of quartz fiber and carbon-based composite material preparation. The preparation method comprises the following steps: carrying out overlapping needling on quartz fiber non-woven cloth or plain cloth with the surface density of 180-600g/m < 2 > and a short quartz fiber web tire with the surface density of 30-150g/m < 2 > to obtain a quartz fiber prefabricated part with the density of 0.35-0.8 g/cm < 3 >, carrying out curing shaping and chemical vapor deposition densification or resin or asphalt impregnation-carbonization densification to 1.2-1.6 g/cm < 3 >, carrying out high-temperature treatment for the first time, and machining to the size; and carrying out silica sol pressurization impregnation, drying, curing, sintering, secondary high-temperature treatment and surface polishing to obtain a product with the density of 1.5-1.8 g/cm < 3 >. And the crucible body and the surface basically do not react with silicon steam, so that the service life of the crucible is prolonged.
本发明涉及石英纤维增强炭‑二氧化硅复合材料坩埚及其制备方法，属于石英纤维及炭基复合材料制备技术领域。采用由面密度180～600g/m2的石英纤维无纬布或平纹布加面密度为30～150g/m2短石英纤维网胎交叠层针刺得密度为0.35～0.8g/cm3的石英纤维预制件，经固化定型、化学气相沉积增密或树脂或沥青浸渍‑碳化增密至1.2～1.6g/cm3后，第一次高温处理，机加至尺寸；加压浸渍硅溶胶，干燥‑固化‑烧结，第二次高温处理，表面抛光，得到密度为1.5～1.8g/cm3的产品。坩埚本体及表面与硅蒸气基本不反应，提高坩埚的使用寿命。
