Each application requires a different grade and specification. Share your intended use and target parameters for a suitable product recommendation. Not all grades are interchangeable across applications.

Magnesium Oxide Grade Selection Guide

Choosing the right magnesium oxide grade is the single most important buying decision. Here is what experienced buyers evaluate:

Refractory GradeHigh MgO content, controlled bulk density, specific calcination characteristics. Used in bricks, monolithic refractories, kiln linings.

Agricultural GradeOptimized for soil application and fertilizer blending. Key factors: Mg content, particle size, dispersibility, blend compatibility.

Feed GradeStrict quality control, trace impurity management, feed-grade documentation. For nutritional magnesium supplementation in animal feed.

Industrial GradeGeneral manufacturing, ceramics, specialty compounds. Balance of purity, particle behavior, and cost-effectiveness for process use.
