For manufacturers relying on Magnesium Oxide (CAS 1309-48-4) as a critical raw material, understanding and verifying its quality specifications is paramount. This white powder, MgO, is fundamental to diverse industries, from rubber and ceramics to pharmaceuticals and food. As a dedicated manufacturer and supplier, we emphasize the importance of detailed specifications to ensure optimal product performance and client satisfaction. This guide is designed for procurement specialists and R&D scientists to navigate the essential quality parameters when they seek to buy Magnesium Oxide.

The appearance of Magnesium Oxide is consistently described as a white powder. However, the true measure of its quality lies within its chemical composition and physical properties. Key specifications that manufacturers should scrutinize include:

1. Purity (Magnesium Oxide Content): This is often expressed as a percentage. Industrial grades typically require a minimum purity, for instance, ≥98.0% as per HG/T2573-2012. For pharmaceutical applications, USP grade often requires ≥97.0%. Higher purity levels generally translate to better performance in sensitive applications.

2. Impurity Levels: Critical impurities such as Calcium Oxide (CaO), Iron (Fe), Heavy Metals (as Pb), Chloride (Cl), Sulphates (SO₄), and others must be within specified limits. For example, a low Iron content (e.g., ≤60 ppm for industry grade) is crucial in applications where discoloration is a concern.

3. Loss on Ignition (LOI): This measures the amount of volatile matter lost when the material is heated at a high temperature. A low LOI is generally desirable, indicating a more stable product.

4. Acid Insolubles: The percentage of material that does not dissolve in acid indicates the presence of inert or undesired components.

5. Bulk Density: This property, often expressed in g/cm³, is important for handling, storage, and dosage calculations, particularly in powder processing. Light Magnesium Oxide, for instance, has a lower bulk density than heavy grades.
