How does the 58±0.5% P2O5 content and low impurity levels (Fe <5 ppm, others <1 ppm) impact the performance of strontium metaphosphate in optical glass melting?
The tightly controlled P2O5 content at 58±0.5% ensures consistent glass network formation and stoichiometry, while the extremely low levels of iron (<5 ppm) and other transition metals (each <1 ppm) minimize color centers and absorption losses. This combination is critical for achieving high optical clarity in research-grade glass applications.
Can the particle size of this strontium metaphosphate powder be customized to below 1 μm, and what advantage does this provide?
Yes, custom particle sizes down to 1 μm are available upon request. Finer particles improve dispersion and mixing homogeneity in glass melts, which is particularly important for research-scale optical glass synthesis where uniform composition is required to avoid localized defects.
What documentation is available to verify the batch-specific purity and trace metal content of this powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. The COA verifies the 99.95% purity, iron <5 ppm, other metals <1 ppm, P2O5 content of 58±0.5%, and loss on ignition of 0.43%.
This 99.95% strontium metaphosphate powder provides controlled trace-metal purity (Fe <5 ppm; Co, Ni, Cu, Cd, Cr, Ti <1 ppm each) plus customizable particle sizes down to 1 μm, with a measured P₂O₅ content of 58±0.5% and loss on ignition of 0.43% for optical glass research.
Positive
- Controlled trace-metal purity: 99.95% purity with Fe below 5 ppm and Co, Ni, Cu, Cd, Cr, and Ti each below 1 ppm supports optical glass research where transition-metal contamination can affect optical quality.
- Custom particle size down to 1 μm: Custom particle sizes down to 1 μm are available, allowing the powder granulometry to be matched to the specific melting, mixing, or dispersion requirements of the glass formulation.
Trade-offs
- Measured loss on ignition: The supplied material reports a loss on ignition of 0.43%, which should be considered when handling or thermally processing the powder in batch formulations.
- Research-scope application limit: The stated application scope is optical glass research; no qualification for broader end-use applications is claimed in the provided specification.
