Abstract
Rice husk and rice bran are the main byproducts of grain production and are considered solid biomass resources. The comprehensive utilization of biomass resources has received increasing attention as a solution to current serious environment pollution, resource and energy crises. Bio-based ceramic particles and their composites are important to the comprehensive utilization of rice waste. This study clarified the preparation process of bio-based ceramic particles and summarized their physical and chemical properties. The morphology, composition and structure of bio-based ceramic particles varied at different carbonization temperatures. Adhesives (phenolic resin) can strengthen the hardness of bio-based ceramic particles at optimum temperatures (900-1,000 °C). Bio-based ceramic particles and their composites can be used as functional additives in polymer- or metal-based composites. Bio-based ceramic particles can enhance the mechanical properties, such as hardness and compression strength of composites and reduce stress concentration. The tribological performance of bio-based ceramic particles and composites was studied under different test conditions. The friction reduction and wear resistance of composites were ascribed to the enhancement of composite hardness and the formation of a transfer film on the counter rubbing pair. The detailed wear map was also described under different test conditions. These results are helpful to understand how the development of bio-based ceramic particles and composites is a simple and effective method of comprehensive utilization of rice waste.
