· HoTaO3

HoTaO3 is a rare-earth tantalate ceramic compound combining holmium (Ho) and tantalum (Ta) oxides, belonging to the family of perovskite-related ceramics with potential high-temperature and dielectric applications. This material is primarily investigated in research contexts for high-temperature structural ceramics, advanced dielectrics, and optoelectronic devices, where its rare-earth content and tantalate backbone offer promise for extreme environment resistance and specialized electronic properties. Compared to conventional tantalates and alumina ceramics, holmium tantalate is notable for its thermal stability and potential use in next-generation aerospace and nuclear thermal management systems, though production and cost remain limiting factors for widespread industrial adoption.

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.
