· JVASP-121952· Ho5S7

Ho5S7 is a holmium sulfide ceramic compound belonging to the rare-earth chalcogenide family, materials known for their refractory properties and potential use in high-temperature environments. This composition appears in specialized literature primarily as a research material rather than a widely commercialized engineering ceramic; holmium sulfides are studied for applications requiring thermal stability, optical properties in the infrared spectrum, and potential nuclear or aerospace contexts where rare-earth compounds are leveraged. Engineers would consider this material when standard oxides are insufficient and when the unique electronic or thermal properties of rare-earth chalcogenides justify the cost and processing complexity.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
