국문 초록

In recent years, there has been growing interest in the high value-added utilization of recycled resources and the efficient use of materials. Among various biomass-derived waste resources, rice husk ash(RHA), which contains over 90 % high-purity silica (SiO2), is attracting attention as an alternative raw material for silica supply. RHA is abundantly generated in rice-producing countries such as Vietnam, ensuring stable raw material availability. Currently, silica is an essential material used across industries including glass, semiconductors, and tires, and is primarily supplied from natural silica sand. However, fluctuations in international raw material prices and concerns about resource depletion have raised challenges for stable supply. In this context, RHA is considered a promising alternative feedstock for producing sodium silicate glass cullet, and more recently, its application has expanded into high-value sectors through conversion to porous amorphous nano-silica for advanced applications such as batteries and high-performance tires. This study evaluated the melting characteristics of two types of Vietnamese RHA to support the process design for silica cullet production. Key design and operation parameters for a melting furnace suitable for producing RHA based silica cullet are proposed.
