The metallic oxide of the multiple genera which are chosen from the group which consists of ceramic madreporic body

摘要

Provided is a ceramic porous body which uses a binder made of a glass excellent in acid resistance and alkali resistance which can be used for a long period of time as a filtration filter etc. ??This ceramic porous body is formed from ceramic particles bonded by using a binder which is a glass comprising 5 to 20 mol % of a plural kind of metal oxides, said metal oxides being selected from the group consisting of Li2O, Na2O, K2O, MgO, CaO, SrO and BaO and containing at least two alkali metal oxides among Li2O, Na2O and K20 as an essential component, 3 mol % or more of either or both of ZrO2 and TiO2 as a total amount, and SiO2 and incidental impurities as a balance.
