Characteristics of β-wollastonite derived from rice
This study aims to characterise β-wollastonite that was derived from rice straw ash and limestone and also its bioactivity by soaking in SBF for 1, 3, 5, 7, 14, and 21 days. Rice straw was fired to obtain SiO2 and CaO from calcined limestone. The ratio of CaO:SiO2 was set at 55:45. The precursor mixture was then autoclaved for 8 h at 135C and sintered for

Wollastonite Imerys
Wollastonite is a naturally occurring mineral that is a chemical combination of calcium, silicon and oxygen. Wollastonite is formed when limestone or other high-calcium rocks undergo high temperature and pressure changes sometimes in the presence of silica-bearing fluids such as in skarns or contact metamorphic rocks.
