Iron crystallization glaze is one of the ceramic glazes, which has attracted the attention of the ceramic industry for its unique crystallization effect and various decorative effects. Among them, the phosphorus content is a key parameter, which can affect the crystallization behavior, crystal size and morphology of the iron system crystallization glaze. In order to better control the preparation process of ferrocrystalline glaze, the effect of phosphorus on ferrocrystalline glaze was studied. Kaolin, potassium feldspar, calcite, talc powder and quartz are used as the main raw materials to prepare iron-based crystalline glaze. By adjusting the content of P, the amount, size and shape of crystal precipitation on the glaze are controlled, so as to obtain iron-based crystalline glaze with different decorative effects. Through XRD, SEM and other analytical means to carry out the experiment, it is found that in the absence of phosphorus, the glaze presents a large number of triangular crystals, giving the metal decoration effect. After addition of P, the growth of magnetic hematite crystals was inhibited, and the morphology of magnetic hematite crystals changed into pine branches, pine whiskers and small clusters. Iron ions enter the glaze layer, causing the glaze to change from metallic to brownish yellow, with a decorative effect.
