Matt transmutation glaze and preparation method thereof
By introducing a composite microcrystalline regulator of strontium titanate and cerium oxide and a composite colorant of cobalt oxide and zirconium silicate into the matte kiln-transformed glaze, and adopting a five-stage gradient firing process, the problems of dry and rough glaze surface, single kiln-transformed color and poor glaze matching were solved, achieving a soft matte effect and high yield.

AI Technical Summary
Technical Problem
Existing matte kiln-transformed glazes suffer from problems such as a dry and rough glaze surface, limited kiln-transformed colors, poor compatibility between the glaze and the porcelain body, and low yield.
Method used
A matte kiln-transformed glaze was prepared by using a composite microcrystalline regulator of strontium titanate and cerium oxide, combined with a composite colorant of cobalt oxide and zirconium silicate, and a five-stage gradient firing process.
Benefits of technology
It achieves a soft, matte dark gray glaze effect with natural kiln-transformation texture, improves the mechanical properties and yield of the glaze layer, and reduces industrial costs.

Abstract
The invention discloses a matt transmutation glaze and a preparation method thereof, and belongs to the technical field of transmutation glazes, the matt transmutation glaze comprises the following preparation raw materials by mass: 38-45 parts of hard feldspar, 20-28 parts of calcite, 10-18 parts of kaolin, 6-14 parts of borocalcite, 13-21 parts of strontium carbonate, 1-5 parts of nano zirconia, 5-10 parts of a composite colorant, 2-6 parts of a microcrystalline regulator, and 1-3.5 parts of a fluxing regulator. The preparation method comprises the following steps: S1, carrying out wet grinding on pretreated preparation raw materials, and aging to obtain glaze slip; s2, glazing the surface of the biscuit by adopting high-pressure glaze spraying to obtain a glazed green body; and S3, carrying out gradient firing on the glazed green body, wherein the gradient firing comprises a low-temperature preheating section, an oxygenolysis section, a high-temperature melting section, a microcrystal precipitation section and a cooling section. The technical problems of dry glaze surface, single transmutation color, poor glaze blank matching property and low yield of the existing matt transmutation glaze are solved, and the glaze surface has transmutation texture and high mechanical property.
