What are the principles of the preparation of ceramic frit RO and RO2 ratio of 1, 1:1 and 1:3 in frit must be in between. 2, RO K 2 O, Na 2 O and RO group in the compound metal oxide ratio shall not exceed 1:1. Alkali metal oxide and boron oxide in the proportion of 3, frit glaze, and the same percentage of alkali metal oxide boron. This provision is to specify all the alkali oxide and boron oxide shall be made of frit, if there is a part of the alkali metal oxide is added to feldspar, can consider to change. 4, acid in the frit containing SiO 2, if adding B 2 O 3 B 2 O 3 and SiO 2 in the proportion of not more than 1:2, because SiO 2 borate quite easy to dissolve, the amount should be at least two times in the B 2 O 3, in order to form insoluble frit. 5, AL 2 in frit O 3, not more than 0.2 molar equivalent of AL 2 O 3, if too much, difficult and easy to melt into a very viscous frit.
