Frequently Asked Questions

What is Caustic Calcined Magnesite used for?

It is used in environmental applications, agriculture, and chemical processes due to its high reactivity and MgO content.

How is Dead Burned Magnesite different from Fused Magnesite?

Dead Burned Magnesite is sintered at high temperatures, while Fused Magnesite is melted in an electric arc furnace, resulting in larger crystals and higher density.

Can you customize product sizes?

Yes, we offer custom specifications for ball sizes, granulation, and chemical composition upon request.

Where is your facility located?

Our production facility is located in Pai Lou Town, Haicheng City, Liaoning Province, China.
