Sanitary ceramic formula and preparation method
The invention relates to the field of preparation processes of sanitary ceramics, in particular to a formula and a preparation method of sanitary ceramics, which improve the refractoriness of a greenbody and reduce the deformation degree of the green body by adjusting the raw material composition of the formula and optimizing the chemical composition. In the mineral composition of a common feldspar porcelain body, a proper amount of wollastonite raw material is introduced, the content of an anorthite crystalline phase is increased on the basis of original mullite and quartz crystalline phases, and a proper amount of closed independent pores are formed, so that the shrinkage rate and the volume density are reduced; by introducing a proper amount of the borocalcite flux, an (O = B-O-B = O)structure can be provided, the integrity and compactness of a network structure around the pores of the borocalcite flux are ensured, and the sizes of the independent pores are controlled within a certain range so as to avoid reduction of the firing strength.
本发明涉及卫生陶瓷制备工艺领域，尤其涉及一种卫生陶瓷配方及制备方法，通过调整配方原料组成、优化化学组成，提高了坯体本身的耐火度，降低了其变形度；在普通长石质瓷坯体的矿物组成中，通过引入适量硅灰石原料，由原有莫来石、石英结晶相的基础上增加了钙长石结晶相含量，形成适量的闭合独立气孔，从而降低了收缩率和体积密度；引入适量硼钙石熔剂，它可提供(O＝B‑O‑B＝O)结构，保证其气孔周围网络结构的完整性和紧密程度，使独立气孔的大小控制在一定范围，以避免烧成强度的降低。
