The invention relates to a method for producing a fused silica ceramic crucible, which belongs to the technical field of a nonmetallic material. The method comprises the steps of: blending fused silica ceramic powder with a grain composition and a premix liquid to prepare a sizing agent, and then carrying out vacuum defoaming, pouring, curing, demoulding, drying and sintering to produce a silica ceramic crucible. In the method, the fused silica ceramic powder with a grain composition is used as a raw material, and thus the produced crucible has a uniform organizational structure, excellent thermal shock resistance, high temperature resistance and chemical stability and can meet the process requirements for the production of polysilicon. The method has the advantages of simple process, short production period and low cost and is suitable for industrialized application.
