ALUMINA GERMANIUM CERAMICS COMPOSITION, ALUMINA GERMANIUM CERAMICS SINTERED ARTICLE, AND SHOWER HEAD USING SAID ALUMINA GERMANIUM CERAMICS SINTERED ARTICLE

摘要

Provided are an alumina germanium ceramic composition and an alumina germanium ceramics sintered article which elute a germanium ion into water by the contact with the water, and a shower head using said alumina germanium ceramics sintered article. An alumina germanium ceramics composition which comprises 60.0 to 90.0 wt % of an alumina powder, 10 to 40 wt % of a germanium oxide powder and 10 to 20 wt % of a silicon dioxide powder. An alumina germanium ceramic sintered article prepared by firing said alumina germanium ceramic composition. A shower head (10) which has a water introducing port (16), a water spraying port (30) and a water flow path formed from the introducing port (16) to the spraying port (30), wherein the above alumina germanium ceramic sintered article (34) is arranged in the course of the above flow path.
