Anti-corrosion coating for aluminum-magnesium-silicon sagger
The invention belongs to the technical field of saggers for synthesizing lithium battery cathode materials, and provides an anti-corrosion coating for an aluminum-magnesium-silicon sagger. The anti-corrosion coating for the aluminum-magnesium-silicon sagger is used for directly modifying the surface layer of the aluminum-magnesium-silicon sagger, so that the aluminum-magnesium-silicon sagger has an excellent anti-erosion tissue structure and chemical composition; the anti-corrosion coating comprises the following solid raw materials: 30-70% of alkaline earth metal salt; 20%-40% of TiO2; 2%-10%of SiO2; 5%-10% of Al2O3; 1%-5% of borax; 0.1%-0.3% of a dispersing agent; and 0.3%-10% of a binding agent. The anti-corrosion coating further comprises water, and the addition amount of the water is10-40% of the total weight of the solid raw materials. According to the coating, the surface of the aluminum-magnesium-silicon sagger is modified, so that the aluminum-magnesium-silicon sagger has excellent lithium corrosion resistant chemical composition and structure, meanwhile, the preparation process is simple, low-cost preparation can be realized, and the practical value is achieved.
