This glazed alumina porcelain is characterized by being glazed with a glaze containing iO2 at a ratio of 10 to 15 moles and containing an impurity alkali component of 1% or less.

A mixture of O□, CaO and MgO is used. Of course, they may be melted to form a glass frit. If the composition deviates from the above range, the glaze may devitrify or droop downward during subsequent metallization firing, which is not preferable.

い、１３００〜１５００℃で１−１０時間焼成を行う。The method of applying such glaze raw materials to alumina porcelain is as follows:
Any conventional method may be used. For example, a method may be used in which a slurry is prepared using a dispersion medium such as water and applied using a spray or a brush. A conventional method is used to glaze the porcelain after the glaze has been applied. That is, baking is performed at 1300 to 1500° C. for 1 to 10 hours using an electric furnace or a gas furnace.
以上のようにして、本発明の施釉アルミナ磁器が得られ

知られている。[Effect J] The details of the reason why the surface resistivity of conventional glazed alumina porcelain decreases after Mo-Mn metallization are unknown, but it is thought that it is probably due to the effect of the reducing atmosphere during metallization and the alkaline components in the glaze. It will be done. That is, Mo
-Mn metallization was performed in Hs-N- atmosphere at 1300-
This is done by heating to 1500℃, but at this time the alkaline components in the glaze are reduced and evaporated into a gas phase, which prevents them from condensing on the glaze surface and the inner surface of the cylindrical alumina porcelain (usually unglazed) when cooled. I think so. It is well known that the surface resistivity decreases due to the action of alkaline components and moisture in the air.
本発明の施釉アルミナ磁器の場合、蒸発すべきアルカリ
成分が実質的に存在しないため、上述したようなことが
起こらず、表面抵抗率の低下がないものと考えられる。In the case of the glazed alumina porcelain of the present invention, since there is substantially no alkaline component to be evaporated, the above-mentioned problem does not occur, and it is considered that there is no decrease in surface resistivity.
