About Tantalum chunks, 99.999%

Tantalum chunks (CAS 7440-25-7) is a high-purity metal offered by Vaqora Chemicals at a purity of 99.999%. Its molecular formula is Ta and its molecular weight is 180.95 g/mol. Its systematic (IUPAC) name is tantalum.

In its supplied form it is solid to chunk to pieces. Reported physical data include a melting point of 2996 °C and a boiling point of 5425 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include alloy preparation, evaporation sources, materials research and electronics and thin films. Buyers come mainly from academic and industrial research and metallurgy and mining.

Standard pack sizes are 10 g and 100 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
