The invention relates to high-grade bone porcelain for daily use. A preparation method comprises the following steps: (1) weighting the following raw materials in parts by mass: 19-24 parts of quartz, 10-16 parts of plagioclase, 3-6 parts of chlorite, 1-2 parts of mullite, 35-43 parts of bone meal, 2-4 parts of biotite, 0.2-0.5 part of CMC and 0.1-0.3 part of alexandrite, feeding the raw materials, ball and water according to a ratio of 1: 2: 0.75 into a ball mill for carrying out wet-milling for 10 hours, sieving with a 300-mesh sieve so that the residue on the sieve accounts for 0.2% and removing iron for later use; (2) injecting slurry: injecting the slurry into a die cavity at a pressure of 25-30MPa, after 0.5 hour, taking a green body out and drying; and (3) sintering: feeding the green body into a tunnel kiln, sintering for 5-7 hours at a temperature range of 1300-1350 DEG C and naturally cooling to obtain the high-grade bone porcelain for daily use. The high-grade bone porcelain for daily use prepared by the preparation method has ivory-colored surface and the rate of finished products of 95% and is exquisite and high in grade.
