The main synthetic raw materials for silicon carbide ceramics are quartz sand and petroleum coke. The silicon carbide ceramic manufacturing process mainly includes four types: reaction sintering, pressureless sintering, hot-pressing sintering, and recrystallization sintering. Among these, reaction sintering holds the largest market share, pressureless sintering offers excellent performance, hot-pressing sintering is more costly, and recrystallization […]

— The Widespread Application Value of High-Efficiency, Energy-Saving Modified Bentonite The steel industry is a major consumer of energy and a significant emitter of atmospheric pollutants, making it a key focus for energy conservation and emission reduction efforts. Faced with increasing constraints on resources and the environment, green development has become the only viable path

In polymer engineering, thermal stability is a crucial performance parameter. Various specialized additives are employed to enhance heat-resistance additives in polymeric materials. 1. Silicone Additives These additives feature unique Si-O bonds with exceptional thermal properties (-50°C to 250°C). They significantly improve thermal stability in polymers while maintaining excellent electrical insulation properties. Additionally, they provide superior

What is hard carbon? Hard carbon refers to carbon materials that are difficult to graphitize above 2500°C. It gets its name from its high mechanical hardness. Hard carbon is generally made through heat treatment at 500–1200°C. Sources include resin carbon (phenolic, epoxy, polyfurfuryl alcohol), pyrolytic carbon (PVA, PVC, PVDF, PAN), carbon black, and biomass carbon.
