Slip casting preparation method for high-whiteness earthenware
The invention relates to the field of ceramics, in particular to a slip casting preparation method for high-whiteness earthenware. The method comprises the following steps: selecting mineral raw minerals, namely selecting the following ceramic mineral sources with high purity in parts: 38 to 42 parts of Suzhou kaolin clay, 26 to 30 parts of Pingjiang feldspar, 24 to 33 parts of Jiangxi porcelain stone and 3 to 5 parts of Haicheng talc, performing washing and preparation, treating mud after ball milling by virtue of an additional pressure filtration procedure, performing slip casting to obtain a blank and firing the blank. According to the method, a process flow of sequentially performing high-temperature biscuit firing and low-temperature glaze firing is adopted, the apparent quality of a burnt matrix is similar to that of ceramic whiteware, the section is substantially sintered to be compacted, the whiteness reaches 70 percent, and the water absorption is lower than 0.5 percent; the product has practical value, and is as white and pleasant as cream.
