This invention relates to the field of architectural ceramics technology, disclosing a titanium sphene crystal frit, its preparation method, and its application. The raw materials include kaolin, titanium dioxide, quartz, potassium feldspar, calcite, and wollastonite. By pre-firing the titanium sphene crystal frit using this formula, the titanium sphene crystals are pre-dissolved in the glass phase. During the subsequent glaze firing process at 1200℃, the titanium sphene crystals melt again and precipitate a second time, resulting in an opaque glaze layer. This secondary crystallization enhances the chemical stability of the titanium sphene crystal frit during subsequent glaze firing, leading to a more stable increase in the solar reflectance of the fired glaze. This solves the problem of unstable reflectivity in glazes when directly using titanium sphene powder or combining it with titanium dioxide and titanium frit to directly form titanium sphene crystals during glaze firing.
