Hydrothermal Synthesis of Foshagite (fiber) (4 CaO 3 Si02 H20)
NIPPON KAGAKU KAISHI, 1972 Foshagite fiber was synthesized hydrothermally from mixtures of Ca(OH)2 or CaCO3 and Si02 chemicals at temperatures ranging from 350 to 900°C under water vapor pressures of 10 to 1000 atm for maximum two weeks, using a test-tube type bomb or autoclave. The mixture was charged in a Pt-capsule.
