[0018] According to the mass ratio of 1:8, add ammonium bicarbonate to deionized water, stir and mix to obtain ammonium bicarbonate solution, according to the mass ratio of 1:10, add 1% mass fraction of fluorosilicic acid to the ammonium bicarbonate solution dropwise, control The rate of fluosilicic acid addition is 2mL / min, after the addition is completed. Filter and collect the filtrate, add aluminum sulfate to the filtrate at a mass ratio of 1:5, stir and mix, and centrifuge at 1500r / min, collect the lower precipitate and vacuum freeze-dry for 1 hour to obtain dry particles and ball mill them through a 200-mesh sieve , to get sieved powder; then weigh 45 parts of silicon oxide, 10 parts of boron oxide, 6 parts of potassium oxide, 1 part of aluminum oxide, 6 parts of titanium oxide, 0.5 part of cobalt oxide, 1.0 part of nickel oxide in parts by weight and 2 parts of manganese oxide were placed in a ball mill jar, and after ball milling at 250r / min for 3h, the ball mill powde...
