Description

Bastnasite CAS NO 1299-84-9 is a vital rare earth fluorocarbonate mineral, serving as a primary commercial source for light rare earth elements (LREEs) such as cerium, lanthanum, and neodymium. Its significance lies in providing a concentrated and economically viable feedstock for the extraction of these critical materials, which are essential for modern high-tech and green technologies. This mineral is crucial for manufacturers and processors in the permanent magnet, catalyst, polishing powder, and metallurgical alloy industries, where a reliable supply of high-purity rare earth oxides is paramount.

Application

• Rare Earth Element (REE) Extraction: Primary ore for the production of cerium, lanthanum, neodymium, and praseodymium oxides.
• Permanent Magnet Manufacturing: Source of neodymium and praseodymium for high-strength NdFeB magnets used in electric vehicles, wind turbines, and hard disk drives.
• Catalyst Production: Provides cerium for automotive catalytic converters and fluid catalytic cracking (FCC) catalysts in petroleum refining.
• Polishing Compounds: Raw material for manufacturing high-performance cerium oxide-based polishing powders for glass, lenses, and semiconductors.
• Metallurgical Alloys: Used as an additive to improve the strength and workability of magnesium and aluminum alloys.
• Phosphors and Lighting: Source of rare earths for phosphors in LEDs, fluorescent lamps, and display screens.
• Glass Additives: Cerium from bastnasite is used for UV absorption and decolorization in specialty glass.
• Research & Development: Serves as a standard or starting material in geological studies and new material science research.

Quality Control

Our Bastnasite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and high rare earth content. Quality is verified through a combination of X-ray fluorescence (XRF), X-ray diffraction (XRD), and inductively coupled plasma (ICP) analysis to determine precise elemental composition and mineralogical purity. We provide comprehensive Certificates of Analysis (COA) detailing total rare earth oxide (TREO) percentage and individual REE distributions to meet the specific requirements of our processing partners.

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. As a mineral product, it is generally stable under these conditions, but protection from excessive moisture and dust contamination is recommended to maintain purity.
