Description

Riebeckite is a sodium-rich member of the amphibole group of silicate minerals, recognized for its fibrous crystal habit and distinctive blue to blue-green coloration. This mineral is of significant industrial interest due to its unique physical and chemical properties, which make it valuable in specialized material applications. Key industries that utilize Riebeckite CAS NO 17787-87-0 include advanced ceramics, specialized pigments, and as a component in certain geological and construction materials.

Application

• As a specialized pigment and colorant in ceramics, glass, and coatings, providing stable blue hues.
• As a reinforcing fiber or filler in composite materials and certain cement formulations.
• In geological and petrological studies as a reference mineral and for academic research.
• As a raw material in the production of specialized refractory and high-temperature ceramics.
• Potential use as a sorbent material in specific environmental remediation processes.
• As a minor component in certain types of decorative stone and architectural aggregates.

Quality Control

Our Riebeckite is sourced and processed with a commitment to consistent quality and compositional integrity. Material characterization is performed using techniques such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) to verify mineralogy and elemental composition. Certificates of Analysis (COA) detailing lot-specific parameters are available upon request to ensure it meets your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Due to its fibrous nature, appropriate industrial hygiene practices should be observed to prevent dust generation and inhalation.
