Sodium metaphosphate is hygroscopic and must be stored in a sealed container under dry conditions to prevent moisture uptake. Loss on ignition is 0.33%, indicating minimal volatile content under standard drying conditions.
- Moisture Sensitivity: Store in a tightly sealed container in a low-humidity environment to avoid caking or degradation.
- Contamination Control: Use clean, dry implements when handling to maintain specified low trace metal levels.
Weigh and transfer the crystal under dry conditions to prevent moisture absorption. Use the material directly in glass batch formulations without additional drying if stored properly.
Required Equipment: Analytical balance, Dry, clean spatula, Sealed container
- Inspect container seal
Inspect the container seal for integrity before opening to confirm no moisture ingress has occurred. - Weigh required amount
Weigh the required amount of sodium metaphosphate crystal on an analytical balance using a dry, clean spatula. - Transfer to batch
Transfer the weighed crystal directly into the glass batch formulation, minimizing exposure to ambient air. - Reseal container
Reseal the storage container immediately after use to maintain dryness for subsequent handling.
What does the loss on ignition and P₂O₅ content indicate about Atomfair sodium metaphosphate for optical glass research?
Loss on ignition is specified at 0.33%, indicating low moisture and volatile content, while P₂O₅ content is specified at 69±0.5%, providing tight compositional control. The material is supplied as a white crystal with 99.95% purity and is intended for optical glass research.
Why are the iron and transition-metal impurity limits important for NaPO₃ used in optical glass?
Iron content is <5 ppm and Co, Ni, Cu, Cd, Cr, and Ti are each <1 ppm, which limits trace-metal contamination in the phosphate batch. These specified impurity ceilings support the product's stated application scope of optical glass research.
What packaging and safety documentation are available for this sodium metaphosphate product?
Available package sizes are 500 g, 1 kg, and 5 kg. COA and SDS can be provided upon request for batch-specific confirmation, and custom specifications, quantities, and packaging are available upon request.
Atomfair sodium metaphosphate crystal (NaPO3, 99.95% purity) is assessed for optical glass research, where its low iron and transition-metal impurities and controlled P2O5 content support contaminant-sensitive glass formulations. Available package sizes of 500g, 1kg, and 5kg affect laboratory workflow without changing the chemical specification.
Positive
- Low transition metal impurities: Iron is specified below 5 ppm and cobalt, nickel, copper, cadmium, chromium, and titanium are each below 1 ppm, reducing trace metal interference in optical glass preparation and characterization.
- Controlled P2O5 content and low LOI: P2O5 content of 69±0.5% with 0.33% loss on ignition provides a defined phosphate composition for reproducible glass research batches.
Trade-offs
- Optical glass research scope: The material is intended for optical glass research, so users pursuing other applications must verify its suitability for their specific process conditions.
- Batch confirmation requires documentation request: COA and SDS are available only upon request for batch-specific confirmation, meaning incoming quality verification depends on actively obtaining these documents from the supplier.
