NOVELTY - Preapring ceramic crucible, where the raw material comprises 12 wt.% aedelforsite, 3 wt.% zinc oxide, 12 wt.% aluminum oxide, 3 wt.% talc powder, 30 wt.% left cloud soil, 20 wt.% bauxite, 2 wt.% yellow lake, 16 wt.%, 16 wt.% quartz, and 2 wt.% lithium carbonate. USE - The ceramic crucible is useful for preparing graphene, and special glass, fusion casting of polycrystalline silicon and calcining of lithium limestone material. ADVANTAGE - The method solves the problem that the high temperature resistance is weak, not convenient for preparing graphene. The ceramic crucible prepared by the method can be directly discharged in the water at 800degrees Celsius without frying and not cracking, the heat stability is strong, and it is more durable, it can bear in 1250degrees Celsius environment for multiple work without damage, when manufacturing the graphene efficiency is higher.
