| titleOfInvention | Lead- and cadmium-free glass frits composition |
| abstract | The Pb- and Cd-free glass frit composition according to the invention, with a selectable property profile, is characterized in that it contains 1 to 24 mol% of lanthanum oxide and 0 to 10 mol% of silica as the network-forming oxides in addition to boron oxide and the molar ratio of boron oxide (B 2 0 3 ) to lanthanum oxide (La 2 0 3 ) is in the range from 3 to 1 to 99 to 1. A preferred composition contains essentially no silica. The properties of the compositions, including the softening temperature and the coefficient of expansion, can be easily adjusted by varying the amount of the main components. |
