Product Specification

Commonly Used In Steel Smelting Casting Furnace Lining Flame Equipment Magnesium Oxide (MgO)

Product Description

99.9% pure Magnesium Oxide (MgO) is a high-purity, white, odorless inorganic compound produced through the calcination of high-quality magnesium carbonate or selected magnesium ores at elevated temperatures. This carefully controlled thermal process removes volatile impurities and yields a finely crystalline powder with exceptional chemical inertness and outstanding thermal stability. With a purity level as high as 99.9%, this grade of MgO guarantees minimal trace contaminants, ensuring consistent performance and superior reliability in even the most demanding industrial environments. The material’s unique combination of properties—including high melting point, excellent electrical insulation, good thermal conductivity, and resistance to chemical attack—makes it indispensable for a wide range of advanced applications. In the electronics industry, it serves as a substrate, insulating layer, or dielectric component in thin-film devices and semiconductors. In ceramics, it functions as a sintering aid and grain-growth inhibitor, enhancing the mechanical strength and thermal shock resistance of specialized ceramic bodies. As a refractory material, 99.9% MgO is used in crucibles, furnace linings, and high-temperature kiln furniture, where it withstands extreme heat and corrosive slag environments. In chemical processes, it acts as a catalyst support, adsorbent, or pH regulator in sensitive syntheses. Overall, this ultra-pure magnesium oxide stands as a critical raw material, enabling innovation and quality assurance across multiple high-tech and heavy-industry sectors.

Process Flow

1. Raw Material Selection: High-purity magnesium carbonate or magnesium ore is selected as the primary raw material.
2. Calcination: The selected material is heated in a high-temperature furnace, typically around 800°C to 1000°C, to produce magnesium oxide (MgO) through thermal decomposition.
3. Cooling and Crushing: After calcination, the material is cooled and ground into fine powder to achieve the desired particle size.
4. Purification and Screening: The powder undergoes purification processes to remove impurities, and is then screened to achieve the required particle size and purity.
5. Quality Testing: The final product is subjected to strict quality control tests, including particle size distribution, purity, moisture content, and other physical properties.
6. Packaging: The product is then packaged in moisture-resistant and airtight containers to preserve its quality.

Theory

The production of magnesium oxide is based on the thermal decomposition of magnesium carbonate (MgCO₃) at high temperatures. The process follows the reaction: $MgCO₃\to MgO+CO₂$ By controlling the calcination temperature and duration, high-purity magnesium oxide (99.9%) can be produced, maintaining the integrity of the material and achieving the desired physical properties.
