Embodiment 1
[0022] Raw materials: 42 parts of montmorillonite, 38 parts of talc, 16 parts of quartz, 8 parts of barium carbonate, 12 parts of manganese dioxide, 17 parts of sodium silicate, 35 parts of feldspar, 7 parts of titanium dioxide, and 5 parts of silver nitrate.
[0023] Preparation:
[0024] (1) Mix montmorillonite, talc, quartz, barium carbonate, manganese dioxide, sodium silicate, and feldspar evenly, pass through a 70-mesh sieve, and calcinate at a temperature of 1500° C. for 3 hours;
[0025] (2) adding titanium dioxide and silver nitrate for ball milling, the solvent is deionized water, the rotation speed is 1200r / min, and then dried at 110°C to obtain the final product.
