Abstract

The invention discloses a sulfur-doped tungsten-based ferrous crystal glaze ceramic product with long-acting stable photocatalytic activity and a preparation method thereof. The preparation method comprises the following steps: applying tungsten-based ferrous ceramic crystal glaze with optical functional activity to the surface of a ceramic body; sintering the ceramic body to which the tungsten-based ferrous ceramic crystal glaze is applied; and calcining the sintered ceramic body and sulfur powder in an inert atmosphere to obtain the sulfur-doped tungsten-based ferrous crystal glaze ceramic product with long-acting stable photocatalytic activity.

Description

technical field [0001] The invention belongs to the field of ceramic glaze, in particular to a sulfur-doped tungsten-based ferrous crystalline glaze ceramic product with long-term stable photocatalytic activity and a preparation method thereof. Background technique [0002] In recent years, the building sanitary ceramics industry at home and abroad has made great progress. In addition to the increase in output, there have also been outstanding progress in product gentrification and variety diversification, which are closely related to the advancement of decoration technology and devices. The fierce competition in the ceramic market has spawned many new products, and crystalline glaze is a decorative material that emerges under this circumstance. As a special effect glaze, crystal glaze has unique artistic charm due to its various crystal flowers and unpredictable colorful patterns, and is very popular and appreciated by people. At present, crystalline glaze is mainly used ...
