Research Paper (postgraduate) from the year 2014 in the subject Chemistry - Materials Chemistry, , language: English, abstract: Wollastonite (CaSiO3) has been synthesized by the solid state reaction method at a temperature range of 1050-1250¿ from local raw materials, e.g. silica sand and limestone as well as pure chemicals in the form of carbonate and quartz with and without B2O3 adding as a mineralized. The resulting products are investigated employing XRD and SEM techniques. ß-wollastonite was obtained at 1050¿ and transformed to pseudowollastonite (¿- CaSiO3) at 1150¿ due to the presence of B2O3. While the pure chemicals failed to give wollastonite at this range of temperature 1050-1150¿. As the temperature increased up to 1400¿, both experimental and standard samples have been melted.
