| Abstract: | β-Ca2Si04 can be obtained from a mixture ofCaC2O4-H2O and amorphous silica by firing at 950°C as opposed to a normal sintering temperature around 1450°C. If CaCO3 is used instead of CaC2O4·H2O, four repeated firings under CO2 atmosphere are needed to obtain β-Ca2SiO4. The role of CO2 atmosphere during firing and the influence of specific surface of reactanm on the rate of reaction are discussed. |
