PURPOSE:To obtain a foaming agent with alkali resistance as well as excellent storage stability by using an alpha olefine sulfonate as the foaming agent of an inorg. suspension. CONSTITUTION:As the foaming agent of the suspension suspending an inorg. substance such as a cement or a glass frit, an alpha olefin solfonate shown by the formula I (wherein R is an alkyl group, M is a base such as a metal such as an alkali metal or an alkali earth metal, ammonia or an amine) is used. Because said foaming agent has alkali resistance as well as storage stability, a foam has stability as well as good flowability. |
