Title (EN) METHOD FOR PRODUCING ALUMINUM TITANATE CERAMIC SINTERED BODY, AND ALUMINUM TITANATE CERAMIC SINTERED BODY
(FR) PROCÉDÉ DE FABRICATION D'UN CORPS FRITTÉ CÉRAMIQUE EN TITANATE D'ALUMINIUM, ET CORPS FRITTÉ CÉRAMIQUE EN TITANATE D'ALUMINIUM
(JA) チタン酸アルミニウム系セラミックス焼結体の製造方法およびチタン酸アルミニウム系セラミックス焼結体
Abstract:
(EN) Disclosed is a method for producing an aluminum titanate ceramic sintered body, wherein the shrinkage of a green body during sintering is reduced.  Also disclosed is an aluminum titanate ceramic sintered body having a low thermal expansion coefficient and a high porosity.  In the method for producing an aluminum titanate ceramic sintered body, 2-25 parts by weight of an inorganic oxide powder is mixed per 100 parts by weight of an aluminum titanate ceramic powder, the thus-obtained mixture is formed into a green body, and the thus-obtained green body is sintered.  The aluminum titanate ceramic sintered body is obtained by the method.
(FR) L'invention concerne un procédé de fabrication d'un corps fritté céramique en titanate d'aluminium grâce auquel le rétrécissement d'un corps vert pendant le frittage est réduit. L'invention concerne également un corps fritté céramique en titanate d'aluminium de faible coefficient de dilatation thermique et de porosité élevée. Dans le procédé de fabrication d'un corps fritté céramique en titanate d'aluminium, on mélange 2-25 parties en poids d'une poudre d'oxyde inorganique pour 100 parties en poids d'une poudre céramique en titanate d'aluminium, le mélange ainsi obtenu est conformé en un corps vert et le corps vert ainsi obtenu est fritté. Le procédé permet ainsi d'obtenir le corps fritté céramique en titanate d'aluminium.
(JA)  焼結の際の成形体の収縮率が低減されるチタン酸アルミニウム系セラミックス焼結体の製造方法および低い熱膨張係数および高い気孔率を有するチタン酸アルミニウム系セラミックス焼結体を提供することを目的とする。本発明は、チタン酸アルミニウム系セラミックス粉末100重量部に対し2~25重量部の無機酸化物粉末を混合し、得られた混合物を成形し、得られた成形体を焼結させる、チタン酸アルミニウム系セラミックス焼結体の製造方法、ならびに、当該方法で得られたチタン酸アルミニウム系セラミックス焼結体である。
