Latest Patents
Shaun Wingfield holds a patent for a unique glass composition. This on-glaze low expansion glass flux composition is suitable for coating onto a glazed surface. It comprises, in mole percent, SiO.sub.2: 35 to 75%, Bi.sub.2 O.sub.3: 4 to 12%, Al.sub.2 O.sub.3: 2 to 12%, and B.sub.2 O.sub.3: 18 to 35%. The composition also includes at least one of Li.sub.2 O, Na.sub.2 O, K.sub.2 O in a total of 0 to 12%. Notably, it avoids containing BaO in amounts exceeding 2 mole percent. The total amount of Bi.sub.2 O.sub.3, B.sub.2 O.sub.3, and alkali metal oxides is maintained between 25 to 45 mole percent. This innovative composition has a coefficient of thermal expansion ranging from 4.0 to 7.0 × 10.sup.-6 /.degree.C, making it particularly useful for enamel compositions in low-expansion porcelain ware.
