Characterization and Comparison of Areca Sheath Ash (ASA) and Rice Husk Ash (RHA) for Silica Potential

Abstract

Utilization of agricultural by products as a reinforcement which offers a effective consequences on composite materials in the present days. Also a number of the agro waste substances as an ash are secondary filler material for Metal matrix composite materials. In this paper observe changed into achieved on characterization of agriculture waste ashes like Rice husk ash (RHA) and ASA (Areca sheath ash), burned at Controlled temperatures at 650°C in a metallurgical furnace at 3 exceptional durations of instances like 1hr, 2hr, and 3hr. Also each ashes were chemically and physically characterized, consequently decide the proportion of composition. The ensuing ashes have been analyzed the use of chemical evaluation via XRF and volumetric, gravimetric and instrumental test, SEM and EDS to determine their chemical composition which may be similarly used as reinforcement with metal matrix composites. Results acquired that impact of burning temperature and time on Chemical composition, Physical property, Loss of ignition (LOI) and Density. The ashes have been discovered to include excessive percent of silica content of 90% to 92% in Rice husk ash and 74% to 78% in Areca palm leaf sheath ash, after which accompanied through alumina content of 0.89% to 0.98% in each substances at 650oc temperatures respectively, additionally density of 0.98gm/cc for RHA and 1.12gm/cc Areca palm leaf sheath ash. Loss on ignition (LOI) of 4.5% to5.5% acquired on the equal temperature. These consequences suggests that rice husk ash and Areca sheath ash include excessive percent silica and a few alumina and may be utilized in chemical formulations requiring silica which include in metal matrix composites.
