Corrosion-resistant protective layer of crucible
The invention discloses a corrosion-resistant protective layer of a crucible, which belongs to the technical field of lithium battery preparation. The corrosion-resistant protective layer of the crucible comprises the following components in percentage by weight: 10 to 20 percent of cordierite, 15 to 29 percent of fused spinel, 5 to 15 percent of M70 mullite, 5 to 15 percent of white corundum, 5 to 10 percent of andalusite, 2 to 8 percent of kaolin, 10 to 30 percent of alpha-aluminum oxide, 2 to 20 percent of potassium feldspar and 10 to 20 percent of kaliophilite. According to the corrosion-resistant protective layer of the crucible provided by the invention, a certain amount of kaliophilite is added, the kaliophilite is rich in K element, and after the kaliophilite is combined with otherraw materials, the reaction between the inner wall of the crucible and a ternary material is weakened, the corrosion of a positive electrode material to the crucible is reduced, the long-term normaluse of the crucible is ensured, and meanwhile, the corrosion resistance of the crucible is improved.
本发明公开了一种坩埚耐腐蚀保护层，属于锂电池制备技术领域，该坩埚耐腐蚀保护层包括以下重量百分比的组分：10‑20％的堇青石、15‑29％的电熔尖晶石、5‑15％的M70莫来石、5‑15％的白刚玉、5‑10％的红柱石、2‑8％的高岭土、10‑30％的α‑氧化铝、2‑20％的钾长石和10‑20％的钾霞石。本发明提供的坩埚耐腐蚀保护层，通过添加一定量的钾霞石，钾霞石中富含有较多的K元素，其与其他原料结合后使得坩埚内壁与三元材料反应减弱，降低了正极材料对坩埚的侵蚀，保证了坩埚的长期正常使用，同时增加了坩埚的抗侵蚀性。
