Patent ID: 7262143

Claim:
A semiconductive glaze product comprising: a glaze composition including a KNaO—MgO—CaO—Al 2 O 3 -SiO 2 -based base glaze and a metal oxide composition including tin oxide and antimony oxide, wherein relative compositional proportions of the base glaze, as represented by the Seger formula of basic components, include KNaO in a range of 0.1 to 0.4, MgO in a range of 0.2 to 0.6, CaO in a range of 0.2 to 0.7, Al 2 O 3 in a range of 0.5 to 0.9 and SiO 2 in a range of 4 to 7; and a flux in an amount of 10 parts by weight or less based on 100 parts by weight of the glaze composition.
