Briefing
High-quality Magnesium Oxide Gray Granular (MgO) – ideal for refractory, steel, and rubber industries. Our premium-grade mag oxide offers high purity, thermal stability & bulk supply options. Trusted by global B2B buyers.
Detailed
Magnesium Oxide Gray Granular
Magnesium Oxide Gray Granular (MgO) is a high-purity, thermally stable chemical compound in granular form, widely used in refractory, steelmaking, rubber, and environmental protection industries. It is produced through calcination of magnesite, offering excellent heat resistance, alkalinity control, and durability.
Magnesium Oxide Gray Granular - Core Features & Competitive Advantages
1. Ultra-High Purity (≥95% MgO Content)
Our Magnesium Oxide Gray Granular undergoes strict calcination control to achieve minimum 95% purity, with premium grades reaching 98%+. This ensures:
Superior chemical reactivity for industrial processes
Minimal impurities (<1.5% CaO, <0.5% SiO₂)
2.Exceptional Thermal Stability (Up to 2800°C)
The dead-burned manufacturing process gives our MgO granules unmatched:
Refractoriness under load (RUL): 1600°C+
Thermal shock resistance for furnace linings
Slow degradation rate in continuous high-temp operations
3.Optimized Granule Physics (3-5mm Standard Size)
Precisely graded granules provide:
✔ Uniform bulk density (1.8-2.2 g/cm³)
✔ Low dust generation - safer handling
✔ Controlled porosity (15-20%) for better slag penetration in steelmaking

Application
1）Agricultural Applications & Fertilizer Use
Ferrous sulfate monohydrate is widely used in agriculture as a source of iron fertilizer to enrich soil with iron. It helps improve photosynthesis and plant growth, particularly in soils suffering from iron chlorosis.
2）Animal Feed & Healthy Animal Feed Blocks
Ferrous sulfate monohydrate is used as an animal feed additive to provide essential iron, especially for animals with iron deficiency, such as poultry and swine. Iron is a critical component of hemoglobin in animal blood, and its deficiency can lead to anemia.
3）Industrial Applications
In industrial applications, ferrous sulfate monohydrate is widely used in water treatment, wastewater treatment, and soil remediation. It effectively removes heavy metal ions from water, particularly when treating water and soil contaminated with excessive heavy metals, due to its strong precipitation properties.
4）Other Uses
Ferrous sulfate monohydrate is also used as an iron source in food additives, lawn fertilizers, and certain reactions in fertilizer production. It is also employed in the production of certain chemicals, particularly in corrosion protection in the steel industry and in the manufacture of bleaches.

FAQ
What is the typical purity level of your Magnesium Oxide Gray Granular?
Our Magnesium Oxide Gray Granular is available in 95-98% purity grades, with strict control of impurities (CaO<1.5%, SiO₂<0.5%). Higher purity options (99%+) can be customized for refractory applications.
How does your product compare to powdered MgO in steelmaking?
The granular form offers:
✔ Lower dust pollution - improves workshop safety
✔ Controlled dissolution rate - better slag conditioning
✔ Higher yield - reduces material loss by 15-20% vs. powders
Can you provide technical support for refractory design?
Yes! Our engineers offer:
• Free formula optimization based on your kiln conditions
• Lab test reports (thermal shock/compressive strength)
• Trial batch production before mass orders
