Preparation of Magnesia Insulation Materials by Calcination of Walnut Shell Powder by Silica Sol Impregnation

Abstract: In this paper, magnesia porous aggregate was prepared by the foaming method with potassium oleate as the foaming agent. Secondly, the walnut shell powder was impregnated with the silica sol as the pore forming agent, and then, a new magnesia insulation material was prepared by 1300°C sintering. By changing the amount of the walnut shell powder added, the mechanical properties and thermal properties of the materials after sintering were studied. The results show that the sample with 10% walnut shell powder impr… Show more

“…However, there are many pores that can be recognized on the surface of sample S2 (marked by a circle), which is attributed to the light weight of the coffee powder and its known tendency to agglomerate in water [28,29], so its compatibility with TEH resin system was poor. Compared with S2 and S3, there were no pores or cracks on the surface of the S1 sample; however, the walnut shell powder-based wheel was hard [30,31], whereas the powder shape was not uniform and the distribution in the TEH system was uneven, where some portions of the resins were not filled with the walnut shell powder. In the case of sample S4, although there were tiny pores (indicated by arrow), the wood powder was evenly dispersed in the TEH resin.…”
