Potassium tantalate (KTaO3) is an inorganic compound composed of potassium ions (K+) and tantalate ions (TaO3-). It is a functional material with important physical and chemical properties.
Potassium tantalate is a crystalline material with a crystal structure similar to that of perovskite. VIMATREIAL also provides a series of other perovskite-structured materials, such as barium titanate (BaTiO3), strontium titanate (SrTiO3), strontium chromate (SrCrO3), etc. If you need it, please contact us.

1. Dielectric material: Due to its high dielectric constant and low loss characteristics, potassium tantalate is used as a dielectric material in capacitors, piezoelectric ceramics, supercapacitors and other fields.
2. Piezoelectric materials: Potassium tantalate has a piezoelectric effect, so it can be used in piezoelectric sensors, pressure sensors, and acoustic wave generators.
3. Optical materials: Due to its optical properties and electrical properties controlled by light, potassium tantalate can be used in optical devices, optical waveguide devices, and photoelectric sensors.
4. Electronic devices: Potassium tantalate can also be used in electronic devices such as field effect transistors (FETs) and phototransistors.
Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Inner vacuum packaging, outer carton/wooden box packaging.
Potassium tantalate should be stored in a dry environment and kept away from light.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
