Description

Periclase is a high-purity, synthetic magnesium oxide (MgO) mineral, distinguished by its crystalline structure and exceptional thermal and chemical stability. This material is critical for demanding industrial applications where consistent purity, high refractoriness, and controlled reactivity are paramount. It serves as a fundamental raw material for manufacturers in the refractory, construction, environmental, and chemical processing industries, providing reliable performance under extreme conditions.

Application

• Refractory Bricks and Monolithics: A key component in magnesia-carbon, magnesia-chrome, and other basic refractory formulations for steelmaking furnaces, cement kilns, and glass tanks.
• Construction Materials: Used as a stabilizing agent and fire retardant additive in specialized cements, boards, and panels.
• Environmental Remediation: Employed in wastewater treatment and flue gas desulfurization processes to neutralize acids and precipitate heavy metals.
• Chemical Synthesis: Acts as a catalyst support, a reactant in the production of other magnesium compounds, and a neutralizing agent in various chemical processes.
• Electrical Insulation: Utilized in the production of heating element insulators and other high-temperature electrical components due to its excellent dielectric properties.
• Agricultural & Animal Feed: Serves as a source of essential magnesium in soil conditioners and mineral supplements.

Quality Control

Our Periclase is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Product specifications are verified through advanced analytical techniques including X-ray diffraction (XRD) for phase purity, X-ray fluorescence (XRF) for chemical composition, and laser diffraction for particle size analysis. Certificates of Analysis (COA) documenting purity, chemical assay, and physical properties are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product performance.
