Abstract
PURPOSE: To obtain a hard case for watch having improved corrosion resistance, transparent and high-quality feeling like jewel, by scattering ceramic particles into crystallized glass as a base material.
CONSTITUTION: Colorless or colored transparent crystallized glass is used as a base material, 0W80wt% various kinds of colored ceramic particles depending upon the appearance of a case to be required are dispersed in the material, to give a composite material. Ceramic particles with particle sizes of several micronsW1mm are used, and their component is zirconia, red lead, yellow titanium, cobalt green, etc. This composite material is molded under heating, and annealed to removed strain, to give a case for watch.
