What particle-size specification is provided for this Si3N4 thermal-spray powder, and what does it mean for spray-process evaluation?
The Atomfair Silicon Nitride Thermal-Spray Powder has a D50 of 2 μm, meaning the median particle size is 2 μm. It is supplied with nitrogen content above 39% and is explicitly intended for coating and high-purity quartz crucible spray research, making the D50 specification a key parameter for evaluating spray-process behavior.
Can this 4N silicon nitride powder be used for high-purity quartz crucible spray research without introducing metallic contamination?
Yes. The product is described as intended for coating and high-purity quartz crucible spray research, and it is supplied as a 4N (99.99% purity) grade. The specified impurity limits are Fe ≤5 ppm, Al ≤5 ppm, Ca ≤5 ppm, Mn ≤5 ppm, Cu ≤5 ppm, O ≤1.0%, and C ≤0.2%, which directly supports low-contamination research use.
Are COA and SDS available for batch-specific confirmation of this silicon nitride thermal-spray powder?
Yes. Atomfair states that COA and SDS can be provided upon request for batch-specific confirmation. For institutional purchasing, requesting these documents allows verification of the lot's nitrogen >39%, D50 2 μm, and the 4N impurity specifications before accepting the material.
Atomfair's 4N (99.99%) Si3N4 thermal-spray powder is specified with nitrogen >39%, D50 2 μm, and individual Fe, Al, Ca, Mn, and Cu limits ≤5 ppm for coating and high-purity quartz crucible spray research. Residual oxygen and carbon allowances should be verified against the batch COA before purity-sensitive deposition work.
Positive
- 4N purity with low trace metals: The powder is specified at 99.99% purity with Fe, Al, Ca, Mn, and Cu each limited to ≤5 ppm, minimizing metallic contamination in coating and quartz crucible spray research.
- D50 2 μm for spray-process evaluation: The stated 2 μm median particle size is provided for evaluating thermal spray behavior in coating and high-purity quartz crucible applications.
Trade-offs
- Residual O and C impurity allowances: The specification permits up to 1.0% oxygen and 0.2% carbon, so batch COA values should be verified when deposit purity is critical in high-purity crucible or coating applications.
