Application of laser scanning microscopy in the development of highly abrasion-resistant glazes for fast-fired hard paste porcelain

摘要

To strengthen the competitiveness of porcelain manufacturers in national and international markets with their ever increasing quality requirements, the research presented was aimed at developing highly abrasion-resistant glazes for fast-fired hard paste porcelain. By increasing the degree of cross-linking in the glass structure, it was possible to improve the mechanical abrasion resistance of porcelain glazes. Uniform and defect-tree glaze application is particularly important for achieving this improvement. To determine the abrasion resistance of the glazes, a new testing method was developed in which the glaze surface is analysed topographically with a laser scanning microscope before and after defined sandblasting and the roughness parameters compared. The glaze development work could be minimized with the help of fractional factorial statistical test planning according to the Taguchi method.
