The Preparation and Properties of Newfashioned Porcelain Powder

The pure leucite and porcelain frit were prepared.In addition,the newfashioned porcelain powder had been prepared by mixing the different ratios of leucite and porcelain frit.The leucite crystal phase and porcelain frit were analyzed by XRD,and coefficient of thermal expansion of the porcelain powder were measured too.The coefficient of thermal expansion of the porcelain powder prepared by mixing porcelain frit and leucite in different ratios is 12.5×10-6~14.5×10-6/℃,demonstrating that the coefficient of thermal expansion of the porcelain powder could be adjusted by the addition of different ratios of leucite,so as to match with the metal substrate.
