Abstract

Much attention has been paid to the characterization of the structure and properties of rice husk ash (RHA), but little to the burning temperature dependence of its structure and properties. This dependence is important for the structure and property optimization of RHA in a controllable manner. In this paper, we present a research on the burning temperature dependence of RHA. Rice husk (RH) was burned at various temperatures either as received or after pretreatment by HCl washing. The obtained ashes of both groups exhibit a strong burning temperature dependence of the specific surface area and pore volume, based on the N2-sorption results. According to the X-ray diffraction (XRD) results, the short range ordered structure of the rice husk silica (RHS) exhibits a decreased densification with the burning temperature; According to the infrared absorption (IR) spectroscopic results, the Si–O–Si angle of RHS was increased with the burning temperature. Based on this dependence, a decreased burning temperature is highly desirable for applications of RHA in catalysis, absorption, and chemical synthesis as Si source.
