POROUS CERAMIC MATERIALS FOR INVESTMENT CASTING
PROBLEM TO BE SOLVED: To provide methods and compositions for forming porous ceramic articles.SOLUTION: The method comprises: forming a composition including liquid siloxanes, ceramic particles, a catalyst and a pore former; shaping the composition; curing the composition to form a green body; volatilizing the pore former before or after curing the composition; and firing the green body. The pore former is a silicon-bearing agent with an average molecular mass under 1300 g/mol, or a molecule with a molecular mass under 1000 g/mol and a freezing point between -40°C and 25°C that is soluble in the liquid. The composition comprises liquid siloxanes, ceramic particles, a catalyst, and a pore former, and the composition is an agent with an average molecular mass under 1300 g/mol or a molecule with a molecular mass under 1000 g/mol and a freezing point between -40°C and 25°C that is soluble in the liquid.SELECTED DRAWING: None
【課題】多孔質セラミック物品を成形するための方法及び組成物が提供される。【解決手段】本方法では、液体シロキサン、セラミック粒子、触媒及び細孔形成剤を含む組成物を生成し、組成物を成形し、組成物を硬化して素地を形成し、組成物を硬化する前又は硬化した後に細孔形成剤を揮発させ、素地を焼成する。細孔形成剤は、１３００ｇ／モル未満の平均分子量を有する含ケイ素剤、又は上記液体に可溶性で１０００ｇ／モル未満の分子量及び−４０℃〜２５℃の凝固点を有する分子である。組成物は、液体シロキサン、セラミック粒子、触媒及び細孔形成剤を含み、この組成物は、１３００ｇ／モル未満の平均分子量を有する薬剤、又は上記液体に可溶性で１０００ｇ／モル未満の分子質量及び−４０℃〜２５℃の凝固点を有する分子である。【選択図】なし
