The invention relates to the technical field of preparation of ceramics, in particular to a high-strength ice crack type ceramic product and a preparation technology thereof. The high-strength ice crack type ceramic product comprises a blank and a glaze, wherein the blank comprises 58 parts of kaolin, 24 parts of potassium feldspar, 13 parts of quartz, 17 parts of clay, 2 parts of talcum, 15 partsof melting additive, 20 parts of wollastonite, 14 parts of brucite, 10 parts of sodium feldspar, 8 parts of calcium silicate, 8 parts of barium sulfate, and 6 parts of sepiolite; the glaze comprises45 parts of potassium feldspar, 16 parts of montmorillonite, 26 parts of quartz, 39 parts of sodium feldspar, 3 parts of color oxide, 2 parts of sodium hexametaphosphate, 5 parts of talcum, and 20 parts of calcium carbonate. The preparation technology comprises the following steps of S1, preparing of the materials; S2, drawing of the blank; S3, plain firing; S4, glaze applying; S5, firing. The high-strength ice crack type ceramic product prepared by the preparation technology has the advantages that the mechanical strength is high, the color is transparent and clear, and the cracks are fine and regular.
