Ba3MgTa2O9
ceramic· Ba3MgTa2O9
Ba3MgTa2O9 is a complex oxide ceramic compound belonging to the perovskite-related family, combining barium, magnesium, and tantalum oxides into a high-density structure. This material is primarily of research and development interest for microwave and radiofrequency applications, where its dielectric properties make it suitable for resonators and filters in telecommunications; it is also explored in specialized capacitor applications where thermal stability and chemical inertness are required. The tantalum content provides exceptional corrosion resistance and high-temperature stability, making it notable compared to simpler ceramic alternatives in demanding electro-optical and RF device environments.

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.
