High-Purity Fused Magnesium Oxide

Product features:

This product adopts advanced electric melting production process, with a purity of up to 99.8% and uniform particle size distribution. Its dense crystal structure endows excellent thermal shock resistance and high-temperature compressive strength, effectively reducing the shedding rate of refractory linings in steelmaking furnaces and ceramic kilns. The ultra-low impurity content avoids introducing harmful elements during high-temperature use, ensuring the safety and stability of downstream products. Compared with ordinary magnesium oxide products, it has higher active index, which can significantly improve the densification degree of refractory castables and extend the service life of high-temperature equipment. It can be customized according to customer requirements for particle size and packaging specifications to match different application scenarios.
