Sagger, preparation method of sagger and application of sagger in preparation of positive electrode material
The sagger comprises a base body and a coating wrapping the surface of the base body, and the coating is prepared from, by weight, 40-50 parts of stone, 10-16 parts of corundum, 18-24 parts of kaolin, 7-10 parts of nitride, 2-6 parts of metal oxide and 2-6 parts of binder. By changing the formula of the sagger raw material coating, the coating has a good protection effect on a sagger base body under the combined action of corundum, nitride and other raw materials, and damage to the sagger during sintering is reduced as much as possible. Therefore, the use frequency of the sagger is far higher than that of a conventional sagger, the replacement frequency of the sagger is reduced, the production stability is improved, and meanwhile the cost is saved.
本发明公开了一种匣钵，包括基体和包覆在表面的涂层，所述涂层的制备原料以重量份计包括：石材40‑50份，刚玉10‑16份，高岭土18‑24份，氮化物7‑10份，金属氧化物2‑6份，粘结剂2‑6份。本发明通过改变匣钵原料涂层的配方，使涂层在刚玉和氮化物及其他原料的共同作用下对匣钵基体具有良好的保护作用，使得烧结时匣钵受到的损害尽可能降低。因此，本发明中的匣钵使用次数远高于常规匣钵，减少了匣钵更换的次数，提高生产的稳定性，同时节约成本。
