Product DescriptionProduct Overview & Executive SummaryHigh Purity Magnesium Carbonate Granules - Product Datasheet & SpecificationsProduct Name: High Purity Magnesium Carbonate GranulesSynonym: Granular Magnesite, High Purity MgCO3 Granules, Synthetic Magnesium CarbonateChemical Formula: MgCO3CAS Number: 546-93-0EINECS Number: 208-915-9Product Description High Purity Magnesium Carbonate Granules are synthesized by controlled precipitation from purified magnesium sources, followed by filtration, drying, granule formation, and high-temperature refinement. Each granule possesses a dense, smooth surface and uniform internal porosity, resulting in excellent physical integrity and consistent bulk density.The product is characterized by high MgCO3 content (≥99%), extremely low levels of iron, calcium, and sulfates, and superior whiteness (≥95%). With its neutral chemical behavior and controlled thermal decomposition, it serves as a reliable raw material for magnesium oxide sintering, high-purity catalysts, and ceramic insulation coatings.Available in granule size ranges of 0.3–2.0 mm or customized specifications, this product is optimized for automated dosing and uniform dispersion. It is non-hygroscopic, easy to transport, and maintains its structure under mechanical stress.Key FeaturesExceptional Purity: MgCO3 content ≥99.0% with low trace contaminants.Granular Efficiency: Improved flow and handling compared to fine powders.High Whiteness & Uniformity: Excellent optical brightness for premium applications.Low Moisture & Dust: Stable during long-term storage and handling.Controlled Thermal Behavior: Decomposes predictably to high-purity MgO.Tailored Particle Size: Custom granule sizes (0.3–2.0 mm) available upon request.Low Impurity Levels: Minimized Fe, Ca, and SO4 ensures high chemical stability.Excellent Physical Strength: Resistant to crushing and attrition.Detailed Technical Specifications & AnalyticalChemical Composition & PurityParameterSpecificationStandard GradeHigh Purity GradeTest MethodMagnesium Carbonate (MgCO3)≥ 98.0%98.5–99.0%≥ 99.3%GravimetricLoss on Ignition (LOI)32–34%33%33–34%950°C ± 25°CCalcium Carbonate (CaCO3)≤ 0.3%≤ 0.2%≤ 0.1%ICP-OESIron (as Fe2O3)≤ 0.02%≤ 0.015%≤ 0.010%ColorimetricChlorides (as Cl)≤ 0.02%≤ 0.015%≤ 0.01%PotentiometricSulfates (as SO4)≤ 0.05%≤ 0.04%≤ 0.03%GravimetricHeavy Metals (as Pb)≤ 0.001%≤ 0.001%≤ 0.0005%USP/EPArsenic (As)≤ 0.00005%≤ 0.00005%≤ 0.00003%ICP-MSSiO2≤ 0.10%≤ 0.08%≤ 0.05%XRFMoisture Content≤ 0.3%≤ 0.2%≤ 0.1%GravimetricPhysical PropertiesParameterSpecification / Typical ValueTest MethodNotesAppearanceWhite, free-flowing granulesVisualDust-free, consistent shapeGranule Size Range0.3–2.0 mm (customizable)SievingOther sizes availableBulk Density (Loose)0.6–1.0 g/cm3ASTM B527Adjustable during granulationTapped Density0.9–1.2 g/cm3ASTM B527—Whiteness≥ 95%CIE LabHigh brightnessSpecific Surface Area (BET)8–25 m2/gBETControlled porosityOil Absorption25–45 g/100gASTM D281Indicates moderate porosityThermal Decomposition Temp.300–500°CFurnace TestConverts to MgOSolubilityInsoluble in water; soluble in acids——Hardness≥ 3.0 N/granuleCompressionMechanically stableKey Characteristics & Functional Advantages High Purity and Consistency: Ensures reliable performance in high-end processing.Stable Physical Form: Granules maintain integrity under vibration or compression.Predictable Calcination: Converts to reactive or sintered MgO upon controlled heating.Low Contamination Risk: Reduced airborne dust ensures cleaner working environments.Flowability and Dispersion: Enables accurate metering in automated systems.Moisture Resistance: Non-hygroscopic and easily stored.Thermal Stability: Excellent behavior up to decomposition temperature.Primary Applications & Industries ServedHigh-Performance Ceramics: Raw material for sintered magnesia refractories and insulating ceramics.Catalyst and Adsorbent Carriers: Uniform granules enhance dispersion and surface area control.Flame Retardants: Used as a precursor for magnesium hydroxide and oxide additives.Electronic Insulation Materials: Essential for MgO-based coatings and fillers.Pharmaceutical and Nutraceutical Applications: As an antacid and magnesium supplement base.Environmental Applications: Used in flue gas treatment, water purification, and heavy metal adsorption.Packaging, Storage & HandlingPackaging Options:- 25 kg multi-layer kraft bag with PE inner liner- 500 kg / 1000 kg jumbo bag- Customized packaging availableStorage Conditions: Store in a cool, dry, well-ventilated area, away from moisture and acidic gases.Shelf Life: 24 months in sealed packaging.Handling Precautions:- Avoid dust generation during loading/unloading.- Use standard PPE (mask, gloves, goggles).- Keep container closed to prevent contamination.Safety Information (Summary of SDS)GHS Classification: Not classified as hazardous under GHS.Hazard Statements: May cause mild irritation upon prolonged dust exposure.First Aid Measures:- Inhalation: Move to fresh air.- Eye Contact: Rinse with water for several minutes.- Skin Contact: Wash with mild soap and water.- Ingestion: Non-toxic in small quantities; seek medical advice if discomfort persists.Quality Assurance & CustomizationProduction Standards: ISO 9001:2015 certified quality system.Analytical Verification: Each batch accompanied by Certificate of Analysis (CoA) confirming chemical purity and granule uniformity.Regulatory Compliance: Conforms to REACH, RoHS, and ASTM specifications.Customization Options:- Tailored granule size and bulk density.- Optional high-reactivity grade for thermal conversion applications.- Low-iron variant for electronic and optical applications.- Custom packaging for industrial and OEM clients.Disclaimer The data and information are offered in good faith based on our current manufacturing and testing experience.
