Calcium fluoride powder is hygroscopic and may absorb moisture from ambient air, which can affect its optical properties in downstream applications. Storage in a dry, inert atmosphere is recommended to prevent moisture uptake and maintain purity specifications.
- Moisture Sensitivity: The powder's loss on ignition of 0.42% indicates residual moisture or volatiles that may increase upon exposure to humid environments.
- Contamination Risk: Trace metal impurities (Fe, Co, Ni, Cu, Cd, Cr, Ti) are specified below 5 ppm, and cross-contamination from handling tools or containers must be avoided to preserve purity.
This procedure outlines safe handling and storage of calcium fluoride powder to maintain its purity and prevent moisture absorption. Proper techniques ensure the material remains suitable for optical glass and laser crystal synthesis.
Required Equipment: Inert atmosphere glovebox or desiccator, Clean, dry stainless steel spatula, Sealable glass or HDPE container with PTFE liner
- Inspect container upon receipt
Inspect the sealed container for any damage or moisture ingress before opening. - Transfer to inert atmosphere
Transfer the powder to an inert atmosphere glovebox or desiccator immediately after opening to minimize moisture exposure. - Weigh using clean tools
Weigh the required amount using a clean, dry stainless steel spatula to avoid cross-contamination. - Reseal storage container
Reseal the original container with a PTFE-lined cap and store in a dry, low-humidity environment below 25°C.
What purity and trace metal specifications does Atomfair CaF₂ powder meet for optical and laser research?
Atomfair calcium fluoride is supplied as a white powder with 99%-99.99% purity. Iron content is <1.5-5 ppm; Co, Ni, Cu, Cd, Cr, and Ti are each <1 ppm; and loss on ignition is 0.42%. These specifications are intended for optical glass and laser crystal material research.
Can Atomfair CaF₂ powder be ordered with custom particle sizes down to 1 μm?
Yes, custom particle sizes down to 1 μm are available upon request. When requesting a quotation, include the required particle size, quantity, and packaging so the powder can be matched to your optical glass or laser crystal material research requirements.
Are COA and SDS documentation available for Atomfair CaF₂ powder?
COA and SDS can be provided upon request for batch-specific confirmation. This documentation supports verification of the stated purity and impurity specifications before use in research workflows.
This CaF2 powder delivers 99-99.99% purity with sub-ppm transition metal levels and particle sizes customizable down to 1 μm, making it suitable for optical glass and laser crystal research; the 0.42% loss on ignition is the key process consideration for stoichiometric melt or sintering routes.
Positive
- Sub-ppm transition metal purity: Iron is specified at <1.5-5 ppm and Co, Ni, Cu, Cd, Cr, and Ti are each below 1 ppm, minimizing trace-metal contamination for sensitive optical and laser crystal applications.
- Custom particle sizes down to 1 μm: Particle size can be tailored down to 1 μm to match powder characteristics to specific processing routes such as sintering, hot pressing, or crystal growth.
Trade-offs
- Loss on ignition of 0.42%: The 0.42% loss on ignition represents a volatile fraction that must be factored into batch stoichiometry and may require pre-drying or outgassing before high-temperature processing.
