SD-HM.SD-HM was established on October 30, 1995, with its registered location in Weifang City, Shandong Province. The company specializes in manufacturing high-tech silicon carbide ceramic products (with its flagship products being reaction-sintered silicon carbide and unpressed sintered silicon carbide products). As a new material, these products exhibit exceptional properties including high strength, high hardness, high-temperature resistance, wear resistance, corrosion resistance, oxidation resistance, thermal shock resistance, excellent thermal conductivity, resistance to thermal shock, and high-temperature creep resistance. They are widely applied across nearly all industrial sectors requiring materials resistant to high temperatures, thermal shock, wear, and corrosion—such as electronics and semiconductors, liquid crystal displays, new energy vehicles, photovoltaic solar energy, metallurgy, chemical engineering, machinery, papermaking, and pharmaceuticals. In recent years, the company's product market has continuously expanded with increasingly diverse applications, now reaching over twenty countries and regions worldwide. Key products include: Reaction-Sintered Silicon Carbide (RSC), Atmospheric Pressure Sintered Silicon Carbide (APS), and Silicon Carbide Micropowder.
