2. Hazards Identification*Classification: not hazardous material pursuant to regulation (EC) no. 1272/2008 EC or EC Directive
67/548/EEC *Compact Metal / Alloy with no Risk to Human Health or the Environment.

3. Composition/Information oningredients*Summary: molybdenum 89,25 % mass fraction, tantalum 10,75 % mass fraction
EC no. molybdenum: 231-107-2, tantalum: 231-135-5
CAS no. molybdenum: 7439-98-7, tantalum: 7440-25-7*Hazardous components: none

4. First-aid measures*Inhalation: no exposure when used as directed. *Skin contact: wash dust off thoroughly with soap andwater. *Doctor is needed or advisable: consult a physician after prolonged exposure to dust.

5. Fire-fighting measures*Suitable extinguishing media: The product itself is not flammable. *Adapt extinguishing measures tosurroundings. *Special hazard: increased fire hazard during dust formation. *Protective equipment:
breathing protection in the presence of dust.

6. Accidental release measures*Personnel-related precautionary measures: dust should be suction cleaned directly at source.
*Environmental protection measures: avoid contamination of agricultural soils (see item 12).

7. Handling and storage*Handling: Avoid dust formation. Use suction cleaning if unavoidable and when processing at hightemperatures (sublimate formation, see item 10). *Storage: no special measures required.

8. Exposure controls/personalprotection*Exposure thresholds: workplace: molybdenum 10 mg/m³ inhalable fraction, mean daily value, tantalum 5
mg/m³ inhalable fraction, mean daily value *Dust-like emissions: General 5 mg/m³ *Wastewater emissions:molybdenum 5 mg/l *Workplace exposure: install suction cleaning when working with dust and sublimate
and use at least one FFP2 respirator. *Environmental exposure: install suction cleaning with filter whenworking with dust formation. *Do not empty into drains.

9. Physical and chemical
properties*Appearance: solid grey material *Melting point: 2630°C *Density: 10,66 g/cm³ at 20°C *Solubility:
insoluble in water, acids and bases; soluble only in complex-forming acids (sulphuric or phosphoric) orbases in combination with a strong oxidizing agent.

10. Stability and reactivity*Conditions to be avoided: high temperatures in air (strong oxidation beginning around 600 °C,sublimation of MoO3 beginning around 700 °C).
*Substances to be avoided: none

11. Toxicological information*No known toxic effects.

12. Ecological information*Ecotoxicity: "molybdenosis (copper deficiency disease caused by Mo in ruminants). *No otherecotoxicological effects. *Mobility: low mobility due to low solubility. *Persistence and degradability:
stable inorganic material. *Bioaccumulation potential: no data available.

13. Disposal considerations*Dispose of residues as metal waste. *Obey national or regional regulations.

14. Transport information*ADR / RID / ADN / IATA (ICAO) / IMDG: not a dangerous good pursuant to international transport
regulations.

15. Regulatory information*No labeling required. *The exposure thresholds given under item 8 pertain to Austrian legal regulations.
*Obey national regulations.

16. Other information*Above information corresponds to our current state of knowledge. However, this shall notconstitute a guarantee for any specific product features and shall not establish alegally valid contractual relationship.
*Detailed results of toxicological and ecotoxicological effects are described in the chemical safety report for
REACH registration.
