Abstract

PURPOSE: To produce the title white and dense composition free from nonuniformity of color, difference in color tone and change in color, by blending MgO with TiO2 in a specific ratio to give a mixture, blending the mixture with Al2O3 and calcining in a nonreducing atmosphere.
CONSTITUTION: Al2O3 is blended with a mixture prepared by mixing MgO and TiO2 in a ratio shown in the range of the oblique line by weight base in the figure and an organic molding auxiliary, subjected to cold static pressure molding and calcined in a reducing atmosphere at 1,550W1,750°C for 3W10 hours.
