Solution to Blackening of Zirconia Ceramic Glaze

Solution to Blackening of Zirconia Ceramic Glaze

Zirconia ceramics have a well-known defect, which is product blackening, which can affect their normal use. Therefore, it is necessary to quickly identify the causes of black zirconia ceramics and glaze blackening defects, and take targeted measures to improve the performance of the product. So far, which methods are more effective and worth recommending to everyone?

The raw materials used for ceramic glaze must be carefully selected, and smoking prone materials should be minimized or avoided as much as possible, which can reduce the sensitivity of the raw material components to the atmosphere. At the same time, it is also necessary to control the firing temperature of ceramics. To achieve a completely molten and bright state, it is best to set the firing temperature 10 ℃ lower than the temperature of metal ceramics, in order to greatly reduce the defect of blackening of the glaze surface.

In addition, improving the surface roughness of black zirconia ceramics and controlling the atmosphere in the equipment are also crucial measures, which have a significant effect on controlling the blackening phenomenon of black zirconia ceramics. The above are all helpful in reducing the occurrence of blackening in black zirconia ceramics, so they should all be of concern to everyone.
