Electric Fusion Alumina-Magnesium Spinel

‌Raw Materials‌: Industrial-grade alumina powder, high-quality calcined magnesia powder
‌Production Process‌: Raw material proportioning -- Smelting (high-temperature fusion in an electric arc furnace) -- Cooling -- Crushing -- Sieving

‌Characteristics‌: Good crystallization, uniform structure, high density, good appearance and color, strong corrosion resistance, excellent thermal shock stability

‌Applications‌:

• • High-purity spinel is suitable for preformed products such as gas-permeable bricks, seat bricks, ladle linings, electric furnace tops, refractory materials for rotary kilns and alloy smelting, as well as shaped products containing spinel.

• • Refractory materials: Enhances slag corrosion resistance in ladle linings and high-temperature zones of cement kilns.

• • Ceramic and glass industries: Kiln furniture, transparent ceramics (laser windows, infrared optical components).

• • Electronic materials: Microwave dielectric ceramic substrates.

• • Environmental protection: Catalyst carriers (automotive exhaust purification).

• • Military and aerospace: Missile fairings, high-temperature wave-transparent materials.
