Description

Elbaite is a complex borosilicate mineral and a member of the tourmaline group, recognized for its unique piezoelectric and pyroelectric properties. This material is of significant industrial interest due to its ability to generate an electrical charge under mechanical stress or temperature changes. It is primarily sought by manufacturers in the electronics, gemological, and advanced materials research sectors for applications ranging from pressure sensors to specialized optical components. Elbaite CAS NO 12197-81-8 is valued for its consistent crystal structure and purity, which are critical for reliable performance in technical applications.

Application

• Manufacturing of piezoelectric sensors and transducers for pressure measurement and acoustic devices.
• Source material for high-quality gemstones and decorative minerals in the jewelry industry.
• Component in specialized optical filters and polarizers due to its dichroic properties.
• Raw material for scientific research and advanced material studies in geology and solid-state physics.
• Use in electrostatic dust collection and air purification systems.
• Potential applications in thermoelectric devices leveraging its pyroelectric effect.

Quality Control

Our Elbaite is sourced and processed to meet stringent quality standards for industrial and research use. Each batch is characterized to confirm its chemical composition, crystal structure, and piezoelectric response. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as elemental analysis, crystal phase identification via X-ray diffraction (XRD), and impurity content. Specifications can be tailored to meet the specific requirements of your application, from gemological grade to high-purity technical material.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at ambient temperature (15-25°C). As a mineral powder or crystal, it is generally stable but should be protected from prolonged exposure to high humidity to prevent caking or surface alteration. Keep away from strong acids and bases.
