The invention relates to a method for preparing white ceramic by the use of natural zeolite. The method for preparing white ceramic by the use of natural zeolite is characterized by comprising the following steps of: 1) crushing the natural zeolite, and grinding to 100 meshes to obtain a zeolite powder; 2) preparing a modified zeolite powder by adopting one of the following two method: (1) mixingthe zeolite powder, sodium chloride, sodium hydroxide and water according to the mass ratio of 10: (0.6-10): (2-10): 30-45, heating and stirring for 12 hours, staying for 48 hours, washing by the useof water, and drying to obtain the modified zeolite powder; (2) mixing the zeolite powder, a waste alkali liquor in caustic soda industry and water according to the mass ratio of (10-15): (6-12): 45,heating and stirring for 12 hours, staying for 48 hours, washing by the use of water, and drying to obtain the modified zeolite powder; 3) mixing the zeolite powder and the modified zeolite powder with the modified zeolite powder being 10-90 wt% of the zeolite powder and the modified zeolite powder, tabletting for moulding, and sintering at high temperature to obtain the white ceramic. By the adoption of the method, the white ceramic has high R457 white value, high acid fastness, high alkali fastness and high Shore hardness.
