Quartz crucible repairing material as well as preparation method and use method thereof
The invention discloses a quartz crucible repairing material as well as a preparation method and a use method thereof. The material is prepared from superfine quartz powder, kaolin, aluminum hydroxide, phosphoric acid, a naphthalene water reducer and water. When the material is prepared, aluminum hydroxide and phosphoric acid are heated to react to generate aluminum dihydrogen phosphate transparent viscous liquid, then superfine quartz powder and kaolin are uniformly mixed and poured into the viscous liquid, then the pH value of the system is adjusted to 6.5-7.5, finally, the naphthalene water reducer and water are added, the mixture is stirred into thick paste, and the thick paste is repeatedly kneaded to obtain the material. When the material is used, the material is smeared on a place needing to be repaired and dried in a drying oven, then the place is put into a heating furnace to be heated and sintered, and finally the crucible is cooled and taken out to obtain a completely repaired crucible. The quartz crucible repairing material is scientific and reasonable in component, simple and safe in preparation process and easy to industrially implement, so that the problem of recycling of a damaged crucible is solved.
本发明公开了一种石英坩埚修补材料及其制备方法和使用方法，该材料由超细石英粉、高岭土、氢氧化铝、磷酸、萘系减水剂和水制成。该材料制备时，先将氢氧化铝和磷酸加热反应生成磷酸二氢铝透明粘稠液体，然后将超细石英粉和高岭土混合均匀倒入粘稠液体中，接着调节体系pH在6.5‑7.5，最后加入萘系减水剂和水，搅拌成稠膏状后反复揉捏即得。该材料使用时，将其涂抹在需要修补的地方并在烘箱内烘干，然后放入加热炉中升温烧结，最后降温取出即得到完全修复的坩埚。本发明的石英坩埚修补材料组分科学合理，制备工艺简单安全，具有易于工业化实施的特点，从而解决了破损坩埚的回收再利用问题。
