Preparation method of bulk conductive quartz
The invention relates to a preparation method of bulk conductive quartz, the preparation method mainly comprises the following steps: (1) mixing silicon dioxide nanoparticles, silver nanoparticles, a polyvinyl butyral (PVB) solution and a polyethylene glycol (PEG) solution, uniformly stirring the mixture, and evaporating a solvent to obtain a solid thermoplastic nano composite material; (2) plasticizing and extruding the solid composite material by using an extruder, and changing the solid thermoplastic nano composite material into a granular raw material; (3) carrying out compression molding on the raw materials at 120-150 DEG C to obtain a green body; (4) immersing the green body into water at 35-50 DEG C for 8-12 hours, and carrying out primary solvent degreasing to remove most of the PEG adhesive; (5) carrying out heat preservation for 1 hour in an environment of 550-650 DEG C, and carrying out secondary solvent degreasing to remove the residual PEG adhesive; and (6) sintering the degreased material in a vacuum environment at 1200-1300 DEG C to obtain the bulk conductive quartz. The preparation process is simple and efficient, the energy consumption in the preparation process is low, and the prepared bulk conductive quartz structure is high in precision and small in surface roughness and has wide application prospects.
