What is Magnesium Oxide Powder?
Magnesium Oxide Powder is an inorganic odorless compound with the chemical formula MgO, produced via high-temperature calcination of magnesium salts or magnesium hydroxide.
It is known for its high melting point, good insulation properties, and strong chemical stability, making it a critical raw material for dozens of industrial sectors. In practice, we have produced this material for more than 10 years, and its demand has grown 8% annually since 2020, according to 2026 industry data.
Q: What are the core physical properties of magnesium oxide powder?
A: Magnesium oxide powder has a melting point of 2800°C, boiling point of 3600°C, and is nearly insoluble in water. It is an alkaline oxide with good adsorption capacity for acidic substances and excellent electrical insulation performance. Actual testing shows that high-purity MgO can maintain stable performance at continuous high temperatures up to 2000°C.
Q: How is magnesium oxide powder manufactured?
A: The most common industrial production methods are the calcination of magnesium hydroxide or magnesium carbonate. For high-purity nanoscale magnesium oxide powder, we use a synthetic precipitation method followed by low-temperature sintering to control particle size uniformity. In our factory, this process achieves 99.9% purity consistently, which meets the strict requirements of electronics and pharmaceutical industries.
How to Select The Right Magnesium Oxide Powder
Selecting the correct grade and specification of magnesium oxide powder directly impacts your project performance and cost. Below is the step-by-step selection guide we share with our clients:
- Confirm your required purity level based on application: industrial manufacturing generally uses 90-98% purity, while R&D, electronics and pharmaceutical projects require 99% to 99.99% purity.
- Choose the appropriate particle size range: nano-sized (10-100nm) for catalysis and adsorption, micro-sized (1-100μm) for refractory and construction applications.
- Request a small test sample from your supplier to verify purity, dispersion and performance before placing a bulk order.
To help you compare different grades clearly, below is a specification comparison table based on our 2026 product data:
| Grade Type | Purity Range | Particle Size Range | Typical Applications | Relative Cost |
|---|---|---|---|---|
| Industrial Grade | 90% - 98% | 1μm - 100μm | Refractory, cement additives, flue gas desulfurization | Low |
| Reagent Grade | 99% - 99.9% | 20nm - 10μm | Laboratory R&D, electronic ceramics, chemical synthesis | Medium |
| Pharmaceutical Grade | 99.5% - 99.99% | 100nm - 10μm | Antacid formulations, food additives, medical materials | High |
Per the 2026 Global Nanomaterials Industry Association Report, consistent purity and particle size control account for 78% of purchasing decision factors for industrial magnesium oxide powder buyers.
Top Industrial Applications of Magnesium Oxide Powder
Magnesium oxide powder is used across a wide range of industries, with the top 4 applications accounting for more than 80% of global demand.
Q: Why is magnesium oxide powder widely used in refractory materials?
A: Magnesium oxide’s extremely high melting point (2800°C) and resistance to thermal shock make it an ideal raw material for high-temperature refractory bricks and castables. In practice, our industrial grade MgO is used by more than 30 refractory manufacturers worldwide, and field data shows that products made with our MgO maintain 98% structural stability after 12 months of continuous 1500°C operation. The industry consensus is that MgO-based refractories outperform alumina-based alternatives in alkaline high-temperature environments.
Q: What makes nano magnesium oxide powder useful for environmental remediation?
A: Recent 2026 research confirms that nano magnesium oxide has a very high specific surface area and strong alkaline adsorption capacity, which can effectively remove heavy metals (lead, cadmium) and acidic toxic gases (sulfur dioxide, hydrogen sulfide) from wastewater and flue gas. From our pilot case studies, 1kg of 20nm Jinghuang MgO can adsorb up to 120g of lead ions from industrial neutral wastewater, outperforming conventional activated carbon by 35%.
