The invention discloses a method for recycling waste porcelain, and belongs to the technical field of ceramics. The method comprises the following steps: carrying out mixed reaction on ceramic slurry, graphene oxide and an acid solution, and calcining; the mass ratio of the ceramic slurry to the graphene oxide is (5-6): 1; the ceramic slurry is prepared from the following preparation raw materials in parts by mass: 100 parts of waste porcelain, 70 to 80 parts of kaolin, 25 to 30 parts of bentonite and 20 to 25 parts of tetraethoxysilane; the calcining temperature is 1000 DEG C to 1200 DEG C; the calcining atmosphere is a reducing atmosphere. Other preparation raw materials are fixed through ethyl orthosilicate; the graphene oxide is reduced into graphene by using a reducing atmosphere, so that the strength of the ceramic material is improved. 本发明公开了一种废瓷再利用的方法，属于陶瓷技术领域；该方法包括以下步骤：将陶瓷浆料、氧化石墨烯和酸溶液混合反应后煅烧；所述陶瓷浆料与所述氧化石墨烯的质量比为5～6:1；所述陶瓷浆料包括以下质量份数的制备原料：100份废瓷、70份～80份高岭土、25份～30份膨润土和20份～25份正硅酸乙酯；所述煅烧的温度为1000℃～1200℃；所述煅
