The invention belongs to the technical field of lithium batteries, and discloses a high-temperature-resistant sagger and a preparation method thereof, the high-temperature-resistant sagger comprises asagger substrate and a coating on the surface of the substrate. The sagger substrate is prepared from the following raw materials in parts by weight: 40-60 parts of silicon carbide powder, 30-40 parts of forsterite, 15-25 parts of high alumina, 5-10 parts of yttrium oxide, 5-10 parts of a binding agent and 10-20 parts of water, the coating is prepared from the following raw materials in parts byweight: 40-50 parts of silicon carbide powder, 20-30 parts of magnesium oxide, 10-20 parts of polyacrylate, 5-15 parts of talcum powder, 3-10 parts of graphite, 1-5 parts of sodium carboxymethyl cellulose and 2-8 parts of water. The synthetic process is simple, the sintering process is easy to control, the prepared material is good in uniformity, the high temperature resistance and the corrosion resistance are obviously improved compared with those of a traditional sagger, the repetition frequency and the product quality are obviously improved, the service life of the sagger is prolonged, thethermal shock resistance is excellent, and the sagger surface layer can be effectively prevented from falling off.
本发明属于锂电池技术领域，公开一种耐高温匣钵及其制备方法，包括匣钵基体和基体表面的涂层；所述匣钵基体由如下重量份的原料制备所得：碳化硅粉体40‑60份，镁橄榄石30‑40份，高铝土15‑25份，氧化钇5‑10份，结合剂5‑10份，水10‑20份；所述涂层由如下重量份的原料制备所得：碳化硅粉体40‑50份，氧化镁20‑30份，聚丙烯酸酯10‑20份，滑石粉5‑15份，石墨3‑10份，羧甲基纤维素钠1‑5份，水2‑8份。本发明合成工艺简单，烧结工艺易控，制成的材料均匀性好，耐高温、抗腐蚀相较比传统匣钵明显提升，其重复次数和产品质量明显提高，延长了匣钵的使用寿命；并且抗热震性能优异，可有效地防止匣钵表层脱落。
