It has good electrical insulation, thermal conductivity, chemical corrosion resistance and lubricity, and is chemically inert to almost all molten metals. The oxidation resistance temperature of this product in air can reach 1000 ℃, and it is still stable under 3000 ℃ in inert gas. Potassium dichromate can be used as reference reagent, micro analysis chlorine determination, redox determination, oxidant, and organic synthesis (special product indicators can be customized).
