Low-toxicity gel system gel casting fused quartz ceramic method

Abstract

The invention relates to the technical field of non-metallic materials, and discloses a low-toxicity gel system gel casting fused quartz ceramic method which comprises the following steps: S1, pretreatment: preparing fused quartz ceramic powder and a mixed solution, and weighing 70-80 parts of fused quartz ceramic powder and 20-30 parts of the mixed solution; s2, ball-milling treatment: adding a dispersing agent and grinding balls into a preparation tank, then adding the gelled slurry, and carrying out ball-milling treatment on the gelled slurry; s3, defoaming and exhausting: adding a certain amount of defoaming agent into the prepared slurry, defoaming, and mounting an exhaust pipe at the top of the preparation tank; s4, heating and curing; s5, demolding and drying; and S6, sintering and molding. The low-toxicity gel system gel casting fused quartz ceramic method is high in automation performance, relatively simple in production process and low in cost, the produced quartz ceramic is high in strength, a matrix structure is uniform and durable, the practicability is improved, the toxicity of the fused quartz ceramic is effectively reduced, and the method is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of non-metallic materials, in particular to a method for casting fused silica ceramics with a low-toxicity gel system. Background technique [0002] Fused quartz ceramics is a kind of fused quartz material made of fused quartz as raw material by ceramic production process. Its production process is: preparation of slurry - pouring molding - blank drying - sintering - cutting and grinding - finished product. Generally speaking, molding is a process that changes materials from a fluid pre-molding state (liquid, soft or powder) to solid. There are many types of food that can be molded by injection molding, and most liquid and solid raw materials can be processed by making Formed into a suitable molding precursor and molded by injection molding. [0003] At present, the existing low-toxicity gel system injection molding method of fused silica ceramics has the following problems: low automation performance, com...
