What are the specified Ta, Nb, and total carbon contents in this (Ta,Nb)C solid solution powder, and how do they define its composition?
The powder is specified with Ta 71.5 ± 1.5%, Nb 21.0 ± 1.0%, and total carbon 7.3 ± 0.3%. Free carbon is limited to ≤0.15%, which together define the (Ta,Nb)C solid solution stoichiometry and ensure batch-to-batch consistency for hard alloy additive research.
What are the maximum allowable impurity levels for Co, Mo, Si, Fe, Ni, and Al in this tantalum-niobium carbide powder?
The product specifies impurity limits: Co ≤0.10%, Mo ≤0.10%, Si ≤0.02%, Fe ≤0.10%, Ni ≤0.04%, and Al ≤0.015%. These tight limits are documented for technical review and are intended to minimize contamination that could affect hard alloy performance.
What is the oxygen limit and appearance of this powder, and what batch documentation is available?
The powder is dark grey with an oxygen content of ≤0.30%, a specification relevant for handling and storage to limit oxidation. COA and SDS can be provided upon request for batch-specific confirmation, supporting laboratory procurement and safety protocols.
Atomfair (Ta,Nb)C solid solution powder with controlled Ta/Nb ratio (71.5/21.0 wt%), total carbon 7.3±0.3%, FSSS 2.0–3.5 μm, and low impurity levels (<0.30% O, <0.15% free C) is engineered for consistent hard alloy additive research where compositional uniformity and trace element control are critical.
Positive
- Defined composition with tight tolerances: Ta 71.5±1.5%, Nb 21.0±1.0%, total carbon 7.3±0.3%, and low impurity limits (Co, Mo, Si, Fe, Ni, Al each ≤0.10%) ensure reproducible phase behavior in hard alloy formulations.
- Controlled particle size range: FSSS 2.0–3.5 μm provides a consistent powder morphology suitable for cermet and hard alloy additive research, enabling predictable sintering and densification behavior.
Trade-offs
- Oxygen content requires handling controls: Oxygen ≤0.30% is a typical specification for carbide powders, but residual oxygen can influence carbide phase stability and may necessitate inert atmosphere processing or pre-reduction steps.
- Free carbon may affect carbide purity: Free carbon ≤0.15% is low but non-zero; residual free carbon can alter the intended carbon balance in solid solution carbides, requiring careful monitoring during sintering or additive manufacturing.
