Preparation & Characterization of Insulating Rice Husk Ash Refractory using Rice Husk as Pore Forming Agent

SK Saddam Hossain | Aman Bhardwaj | Manas Ranjan Majhi

Abstract: Preparation of the Insulating Silica Refractory was done by utilizing the waste Rice Husk Ash taken from rice mills. These insulating properties can be obtained by controlling the porosity of the sample by using different amount of rice husk as pore forming media and different firing temperatures. Experimental compositions were prepared by RHA whose chemical composition were determined by X-RF. Rectangular samples were prepared using hydraulic press. Physical properties like Apparent Porosity was found to be favorable for Thermal Insulation and was observed to be increasing with increasing the amount of pore forming agent (Rice Husk). Mechanical strength were found to be good considering the porosity present. In addition the Crystalline phase were also been studied by XRD analysis.
