The invention relates to the field of sanitary ceramic preparation technology, in particular to a sanitary ceramic formula and a preparation method. By adjusting the composition of the formula raw materials and optimizing the chemical composition, the refractoriness of the green body itself is improved, and the deformation degree thereof is reduced; In the mineral composition of the porcelain body, by introducing an appropriate amount of wollastonite raw material, the content of anorthite crystalline phase is increased on the basis of the original mullite and quartz crystalline phases, and an appropriate amount of closed independent pores is formed, thereby reducing the shrinkage rate. and bulk density; introducing an appropriate amount of monetite flux, it can provide (O=B‑O‑B=O) structure, ensure the integrity and tightness of the network structure around its pores, and control the size of independent pores within a certain range. In order to avoid the reduction of firing strength. |
