Tantalum Evaporation Materials Description
Tantal (Ta) is a dark bluish-grey metal. It is heavy, ductile and hard. It exhibits high corrosion resistance and remains chemically stable at temperatures below 150 °C. It can only be dissolved using hydrofluoric acid.
High-purity evaporation materials are important in deposition processes to ensure the quality of deposited layers. Stanford Advanced Materials (SAM) specialises in manufacturing Tantalum evaporation materials with a purity of up to 99.95 %. Quality assurance processes are applied to validate product reliability.
