탄탈 오산화물 C화학적 특성, 용도, 생산
화학적 성질
Tantalum pentoxide, Ta2O5, is a white powder existing in two thermodynamically stable modifications. The orthorombic b-phase changes at 1,360 °C (2,480 °F) into the tetragonal a-modification. The existence of an e-modification has also been reported. Tantalum pentoxide reacts slowly with hot hydrofluoric acid but is insoluble in water and in most solutions of acids and alkalies. For analytical purposes, it can be dissolved by fusion with alkali hydroxides, alkali carbonates, and potassium pyrosulfate.물리적 성질
White orthorhombic crystal or powder; density 8.20 g/cm3; melts at 1,785°C; insoluble in water, ethanol and practically all acids; soluble in hydrofluoric acid; solubilized by fusion with caustic potash or potassium hydrogen sulfate.물리적 성질
Dielectric used in film supercapacitors. Tantalum oxide is a high-refractiveindex, low-absorption material used in making optical coatings in the near-UV (350 nm) to IR (8 μm). Insoluble in most chemicals except HF, HF-HNO3 mixtures, oleum, fused alkali hydroxides (e.g., NaOH, KOH), and molten pyrosulfates.용도
Tantalum pentoxide is used in making high refractive index optical glass; as a dielectric film on tantalum for its use as a capacitor component and rectifier; and for preparing tantalum metal, its carbide, and many other tantalum compounds.제조 방법
Tantalum pentoxide is obtained as an intermediate in extracting tantalum from the columbite-tantalite series of minerals. Also, the oxide can be made by heating Ta metal in oxygen or air at elevated temperatures.일반 설명
Tantalum pentoxide is dielectric in nature making it useful for making capacitors in the electronics industry.위험도
TLV: 5 mg/m3.Safety Profile
Mildly toxic by ingestion. Incompatible with ClF3, BrF3, Li. See also TANTALUM.탄탈 오산화물 준비 용품 및 원자재
