This materials-science paper made phosphate glasses containing zinc, strontium and lithium oxides with small additions of carboxymethyl cellulose and measured their structure, hardness and elastic properties. Strontium oxide is a glass component here, not an exposure studied in food or people.
Key numbers
- This paper reports no numerical findings relevant to strontium exposure.
Methods (brief)
Melt-quenched glasses were characterized by FTIR and Raman spectroscopy, ultrasonic velocity and Vickers hardness.
Evidence fitness
Off-topic for dietary exposure: it supports only materials properties of a strontium oxide glass. It does not support exposure, migration or toxicity claims, and suggested food-processing uses are not tested.
Limitations
No migration, leaching or food-contact testing. Funding included a grant linked to a glass manufacturer. The journal lists the issue as 2024 although indexing metadata gives 2025.
