Embodiment 1
[0027] An ultra-flat glaze frit is prepared from the following raw materials in parts by mass: potassium feldspar: 53 parts, wollastonite: 25 parts, calcined talc: 15 parts, and barium carbonate: 7 parts.
[0028] The firing method of frit is:
[0029] (1) Weigh the raw materials and mix them evenly;
[0030] (2) Melt at a temperature of 1500-1600°C and keep warm for 2-3 hours;
[0031] (3) Water quenching and drying to obtain frit with high initial melting point and low expansion coefficient.
