What are the uses of South Africa chromite sand?
South Africa chromite sand is a high-quality chromite resource, classified as metallurgical-grade and foundry-grade depending on its chromium content. Foundry-grade chromite sand from South Afirca is renowned for its high chromium content (typically 45-46% Cr₂O₃), low silica content (less than 1% SiO₂), and excellent high-temperature resistance. It is widely used in industries such as chemical casting and refractory materials. Its application stems primarily from its core properties: excellent high-temperature resistance, chemical inertness, good thermal conductivity, and high specific gravity.
