Mid-grade magnesite is produced using light-burned magnesia with an MgO content of 95% as the raw material, through processes such as briquetting and firing in a high-temperature shaft kiln. The product exhibits excellent sintering degree and dense crystallization, making it a high-quality raw material for manufacturing mid-grade magnesia-based refractory products.
