Embodiment 1
[0042] Step 1: Magnesium carbonate basic (Mg(OH) 2 4MgCO 3 ·5H 2 O), Li 2 CO 3 , Nb 2 o 5 and TiO 2 , prepare materials according to the mass ratio of 43.95%, 25.71%, 28.69% and 1.65% respectively, the obtained mixture is milled with zirconia balls, and absolute ethanol is used as a solvent, according to the mixture: grinding ball: ethanol The weight ratio was 1:5:2 for grinding for 6 hours, and finally a homogeneous mixture was obtained;
[0043] Step 2: Dry the ball-milled mixture at 100°C and pass through a 60-mesh sieve to obtain a dry powder, then pre-sinter at 1000°C for 3 hours to obtain a sample briquette;
[0044] Step 3: Pulverize the sample burnt block, use zirconia balls as the ball milling medium, use absolute ethanol as the solvent, grind for 2 hours according to the weight ratio of mixture: balls: ethanol is 1:5:2, dry and make Granulation treatment, the granulation size is controlled at 120 mesh, and the granules are put into the forming mold and dry-pres...
