Embodiment 1
[0017] According to the proportion of raw materials, 46% of quartz powder, 12% of potassium feldspar, 8% of kaolin, 15% of wollastonite, and 8% of alumina are weighed and added to the ball mill with high alumina lining and high alumina balls, and the above mixture is added Water ball milling with 50% mass for 24 hours, then add 1% lanthanum oxide, 2% molybdenum trioxide, 1% cerium oxide, 5% zirconium dioxide, and 2% yttrium trioxide, according to the ratio of 1:1 by weight of the above raw materials Add corresponding water, and then ball mill for 8 hours. The particle size of the glaze is controlled to be less than 0.05% on a 325 mesh sieve. Remove iron from the mill and sieve. Apply glaze to the 90 alumina ceramic body by spraying method, the glaze thickness is 25μm, and fire at 1480±10°C for 2 hours.
Embodiment 2
[0019] According to the raw material ratio of 52% quartz powder, 8% potassium feldspar, 7% kaolin, 7% wollastonite, and 12% alumina, weigh each material and add it to a ball mill with high alumina lining and zirconia balls, and add the above mixture 52% by weight of water ball mill for 22 hours, then add 2% of lanthanum oxide, 3% of molybdenum trioxide, 2% of cerium oxide, 6% of zirconium dioxide, and 1% of diyttrium trioxide, according to the ratio of 1:1 by weight of the above raw materials Add corresponding water, and then ball mill for 6 hours to control the particle size of the glaze to be less than 0.05% on a 325 mesh sieve. Remove iron from the mill and sieve. Apply glazing on the 95 alumina ceramic body by spraying method, the glazing thickness is about 15μm, and fire at 1560±10℃ for 1 hour.
Embodiment 3
[0021] According to the proportion of raw materials, 40% of quartz powder, 15% of potassium feldspar, 11% of kaolin, 10% of wollastonite, and 6% of alumina are weighed and added to a ball mill with high alumina lining and zirconia balls, and the above mixture is added 45% by weight of water ball mill for 26 hours, then add 1% of lanthanum oxide, 6% of molybdenum trioxide, 1% of cerium oxide, 8% of zirconium dioxide, and 2% of diyttrium trioxide, according to the ratio of 1:1 by weight of the above raw materials Add corresponding water, and then ball mill for 6 hours to control the particle size of the glaze to be less than 0.05% on a 325 mesh sieve. Remove iron from the mill and sieve. Apply glaze to the 90 alumina ceramic body by spraying method, the glaze thickness is about 35μm, and fire at 1500±10°C for 3 hours.
