What Is Magnesium Oxide?

Magnesium oxide is an inorganic compound consisting of magnesium and oxygen. It generally appears as a white, odorless powder, although its physical characteristics can vary depending on particle size, production method, purity, and processing conditions.

The compound is valued for its ability to withstand high temperatures and its capacity to react with acidic substances under suitable conditions. These characteristics make it useful in applications ranging from refractory materials to water treatment and industrial chemical production.

Magnesium oxide can be manufactured in different grades according to its intended application. Some grades are designed for high-temperature industrial processes, while others are produced for agricultural, environmental, or specialized technical uses.

Selecting the correct grade is important because purity, reactivity, particle size, surface area, and bulk density can significantly influence performance.

Chemical Identity and Key Properties

The chemical identity of magnesium oxide is an essential consideration when purchasing or using this material.

Its molecular formula is MgO, and its CAS Registry Number is 1309-48-4. The compound is classified as an alkaline inorganic oxide.

Magnesium oxide has a high melting point, approximately 2,850°C, making it valuable in applications that require resistance to extreme heat. Its density and other physical properties depend on the material's structure, porosity, and processing history.

Another important characteristic is its reaction with water. Magnesium oxide can gradually form magnesium hydroxide when exposed to moisture, with the reaction rate depending on factors such as temperature, particle size, and material reactivity.

It can also react with acids to form magnesium salts and water. This chemical behavior supports its use in neutralization processes and selected industrial treatments.

Although magnesium oxide is relatively stable under ordinary storage conditions, its performance can change when exposed to moisture or incompatible materials. Appropriate packaging and storage practices help preserve its intended characteristics.

Understanding CAS Number 1309-48-4

A Chemical Abstracts Service Registry Number, commonly called a CAS number, is used to identify a particular chemical substance.

For magnesium oxide, the CAS number is 1309-48-4. This identifier helps distinguish the substance from other compounds that may have similar names or related industrial uses.

CAS numbers are useful in chemical procurement, laboratory documentation, safety data sheets, regulatory records, and international trade communications.

However, a CAS number does not establish the purity, quality, grade, or suitability of a particular commercial product. Buyers should also review the technical data sheet, safety data sheet, certificate of analysis, and other relevant supplier documentation.

These records help confirm that the material meets the requirements of its intended application.

What Does Code 2519909100 Mean?

The number 2519909100 may be used as a customs or tariff classification in certain trade contexts. Such codes help customs authorities classify products for import and export procedures, duty assessment, and statistical reporting.

However, tariff classifications are jurisdiction-specific and can change over time. The correct code may depend on the country's tariff schedule, the product's processing method, composition, intended form, and applicable classification rules.

Businesses should therefore avoid relying exclusively on a product listing or supplier description when preparing customs documentation.

Importers and exporters should verify the classification against the current official tariff schedule applicable to the destination or exporting country. When uncertainty remains, a qualified customs broker or the relevant customs authority can help determine the appropriate classification.

Correct documentation can reduce the risk of customs delays, incorrect duty calculations, and shipment processing problems.

Industrial Applications of Magnesium Oxide
