KTa
ceramic· JVASP-128254· KTa
KTa is a potassium tantalate ceramic compound, a member of the perovskite family of functional ceramics. It is primarily utilized in electro-optic and photorefractive applications where its ability to modulate light under electrical fields is critical, as well as in nonlinear optical devices and acoustic transducers where its piezoelectric properties are leveraged. Engineers select KTa over alternatives like potassium niobate for applications requiring high transparency, strong electro-optic coefficients, and compatibility with laser systems, though its use remains largely specialized to research and high-performance photonics rather than commodity applications.

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.
