Abstract
(EN) 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.
(FR) L’invention concerne une composition de céramique de germanium alumine et un article fritté céramique de germanium alumine permettant d’éluer un ion de germanium dans l’eau par contact avec l’eau, et un pommeau de douche utilisant ledit article fritté céramique de germanium alumine. Elle porte sur une composition de céramique de germanium alumine comprenant de 60,0 à 90,0 % en poids d'une poudre d’alumine, de 10 à 40 % en poids d’une poudre d’oxyde de germanium et de 10 à 20 % en poids d’une poudre de dioxyde de silicium. Elle concerne également un article fritté céramique de germanium alumine élaboré par cuisson de ladite composition de céramique de germanium alumine. Un pommeau de douche (10) possédant un orifice d’introduction d’eau (16), un orifice d’aspersion d’eau (30) et un circuit d’écoulement d’eau formé de l’orifice d’introduction (16) à l’orifice d’aspersion (30), où l’article fritté céramique de germanium alumine (34) ci-dessus est disposé sur le trajet d’écoulement ci-dessus.
(JA)  水と接触してゲルマニウムイオンを水中に溶出するアルミナゲルマニウムセラミックス組成物及びアルミナゲルマニウムセラミックス焼結体と、該アルミナゲルマニウムセラミックス焼結体を用いたシャワーヘッドを実現する。  アルミナ粉末を60.0~90.0wt%、酸化ゲルマニウム粉末を10~40wt%、二酸化ケイ素粉末を10~20wt%の割合で含有するアルミナゲルマニウムセラミックス組成物。当該アルミナゲルマニウムセラミックス組成物を焼成して成るアルミナゲルマニウムセラミックス焼結体。水の導入口16と噴出口30を備え、上記導入口16から噴出口30に至る水の流路が形成されたシャワーヘッドにおいて、上記水の流路の途中に、上記アルミナゲルマニウムセラミックス焼結体34を配置したシャワーヘッド10。
