How does this beta-SiC (3C-SiC) powder’s crystal phase and particle-size distribution affect its use as a thermal-conductive or microwave-absorbing filler?
The product is a cubic beta-SiC (3C-SiC) powder with >98% purity and a D50 of 2.76 μm; the particle-size distribution is D10 1.55 μm, D90 4.62 μm, and D97 ≤5.55 μm. This defined phase and distribution support low oil-absorption behavior and tunable dielectric performance for composite filler evaluation, but thermal-conductivity and microwave-absorption results depend on the final loading and matrix formulation.
Can this product be used in dielectric or insulation materials research without additional purification?
This grade is supplied at >98% purity and is explicitly intended for dielectric or insulation materials research. The declared impurity profile includes Fe₂O₃<0.2%, SiO₂<0.3%, F.Si<0.2%, and F.C<0.05%; for batch-specific qualification, request the COA and SDS before use.
What ordering, documentation, and packaging options are available for this 3C-SiC powder?
The product is offered in 500g, 1kg, and 5kg packages, and custom package sizes may be evaluated on request. COA and SDS can be provided for batch-specific confirmation, and custom particle-size or purity requirements can be reviewed for selected grades through technical sales.
Atomfair Beta Silicon Carbide Powder (3C-SiC) with >98% purity and D50 2.76 μm offers a controlled particle size distribution and low oil absorption, making it suitable for evaluation as a thermal-conductive, microwave-absorbing, or dielectric filler material. The cubic beta-SiC phase and defined impurity profile are the key technical parameters to verify against the target formulation before bulk deployment.
Positive
- Controlled particle size at D50 2.76 μm: Stated D10 1.55 μm, D90 4.62 μm, and D97 ≤5.55 μm define the size envelope, supporting consistent dispersion and packing when evaluated as a functional filler.
- Low oil absorption and tunable dielectric behavior: The powder's low oil absorption enables higher filler loading studies, while the cubic 3C-SiC phase allows tunable dielectric performance for thermal-conductivity and microwave-absorption research.
Trade-offs
- Residual oxides and free silicon impurities: The impurity profile permits Fe2O3 <0.2%, SiO2 <0.3%, and F.Si <0.2%, so applications with tight purity budgets should confirm batch-specific values from the COA before formulation.
