摘要：This work introduces novel method to prepare ecomaterials wollastonite (CaSiO3) using the hydrothermal treatment technique of Rice hush ash (RHA), glass cullet and CaO at 180°C for 24 hour so as the Ca/Si molar ration of 1.0. The sample after hydrothermal treatment at 180°C for 24 hours is calcined at 1000°C to obtained wollastonite CaSiO3. The obtained wollastonite has many applications in biomaterials and thermal insulator. This research also aim to improve the quality of RHA, thus reduce negative impact to environment.
