多孔质陶瓷部件及其制法以及过滤器
摘要：
本发明提供一种气孔率大、平均气孔径大的多孔质陶瓷部件及其制法以及过滤器。将含有Al、Ti、Mg及O的平均粒径25μm以上的钛酸铝型的结晶粒子(11)彼此以含有Si的非晶质材料(13)接合，同时气孔率为35％以上，平均气孔径为5μm以上。在该种多孔质陶瓷部件中，能够形成大的气孔，并且具有充分的气孔率，例如，在作为过滤器元件使用的情况下，能够使气体充分地透过。
摘要（英）：

Disclosed are a porous ceramic member having high porosity and large average pore diameter, a method for producing the porous ceramic member, and a filter. The porous ceramic member is obtained by joining crystal particles (11) of aluminum titanate, which contain Al, Ti and Mg and have an average particle diameter of not less than 25 [mu]m, with an amorphous material (13) containing Si. The porous ceramic member has a porosity of not less than 35% and an average pore diameter of not less than 5 [mu]m. The porous ceramic member has large pores and a sufficiently high porosity, and thus gas cansufficiently permeate therethrough when the porous ceramic member is used, for example, as a filter element.
