Description

Olivine is a naturally occurring magnesium iron silicate mineral prized for its high-temperature stability and chemical inertness. This material is critical for industrial processes requiring durable, refractory materials with excellent thermal properties. It serves as a key raw material in foundry operations as a molding sand, in steelmaking as a slag conditioner, and in environmental applications for carbon sequestration. Our high-purity Olivine CAS NO 19086-72-7 is sourced and processed to meet the stringent demands of these diverse global industries.

Application

• Foundry & Metalcasting: Used as a high-quality, silica-free molding sand for ferrous and non-ferrous metal casting, providing excellent thermal stability and reducing the risk of silicosis.
• Steel Industry: Employed as a slag conditioner and fluxing agent to control slag viscosity and chemistry, improving furnace efficiency and steel quality.
• Refractory Manufacturing: A key component in the production of forsterite bricks and other refractory linings for high-temperature industrial furnaces.
• Carbon Capture & Storage (CCS): Utilized in mineral carbonation processes due to its high reactivity with CO₂, offering a potential route for permanent carbon sequestration.
• Soil Amendment & Agriculture: Acts as a slow-release source of magnesium and iron to correct soil deficiencies and adjust pH in specialized horticulture.
• Abrasive & Blasting Media: Serves as an effective, less toxic alternative to silica sand for surface preparation and abrasive blasting applications.
• Water Filtration: Used as a filter medium for heavy metal removal and pH adjustment in wastewater treatment systems.
• Thermal Energy Storage: Investigated as a packed-bed material for concentrated solar power and other thermal storage systems due to its high heat capacity.

Quality Control

Our Olivine is processed and graded to ensure consistent chemical and physical properties critical for industrial performance. We employ rigorous quality testing protocols, including X-ray fluorescence (XRF) for elemental composition, particle size analysis (PSA), and loss on ignition (LOI) testing. Certificates of Analysis (COA) detailing lot-specific data for MgO, Fe₂O₃, SiO₂ content, and granulometry are available upon request to support your quality assurance and production planning.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids. Although not highly hygroscopic, prolonged exposure to high humidity should be avoided to prevent caking. Store away from incompatible materials.
