ABSTRACT:
A semiconductive glaze product is provided, which exhibits low thermal expansion coefficient without adversely affecting other glaze characteristics, and which, when applied to an insulator, attains enhanced mechanical strength of the insulator. The semiconductive glaze product contains a glaze composition and a flux. The glaze composition contains a KNaO—MgO—CaO—Al2O3-SiO2base glaze, in which the compositional proportions of KNaO, MgO, and CaO, as represented by the Seger formula, are 0.1 to 0.4, 0.2 to 0.6, and balance, respectively. The glaze composition contains a metal oxide composition including tin oxide and antimony oxide, wherein the amount of flux is 10 parts by weight or less on the basis of 100 parts by weight of the glaze composition.
