Description

Pectolite is a complex calcium sodium inosilicate mineral with the chemical formula NaCa₂Si₃O₈(OH). This naturally occurring mineral is valued for its unique fibrous crystal structure and specific chemical composition, making it a material of interest in several industrial and research fields. It is primarily sought by manufacturers and researchers in the ceramics, construction materials, and geopolymer sectors for its role as a precursor or functional additive. Pectolite CAS NO 13816-47-2 offers a consistent and reliable source of specific silicate chemistry for advanced material development.

Application

• Ceramics and Glass Manufacturing: Acts as a fluxing agent and a source of sodium and calcium oxides to modify melting points and improve the physical properties of final products.
• Geopolymer and Alkali-Activated Binders: Serves as a reactive aluminosilicate precursor for producing low-carbon cementitious materials and specialty concretes.
• Mineral Wool and Insulation Materials: Used in the formulation of high-temperature stone wool insulation due to its specific melting characteristics and chemical stability.
• Catalyst Support Substrate: Its fibrous structure and chemical inertness make it suitable as a carrier for certain heterogeneous catalysts.
• Dental and Biomedical Composites: Investigated as a biocompatible filler material in restorative cements and bone graft substitutes.
• Soil Amendment and Agriculture: Provides a slow-release source of calcium and silicon, which can benefit plant growth and soil structure.
• Research and Development: Utilized in geological studies, material science research, and as a standard in analytical chemistry.
• Abrasive and Polishing Compounds: The mineral's hardness and particle morphology are leveraged in fine polishing applications.

Quality Control

Our Pectolite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and purity for industrial applications. While specific grades are available, all material is subject to rigorous analytical testing including X-ray diffraction (XRD) for phase identification and X-ray fluorescence (XRF) for elemental composition. Certificates of Analysis (COA) detailing lot-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture and carbon dioxide.
