High-Purity Silicon Carbide 90% Powder (0-1mm) - Accelerated Deoxidizer for Precision Metallurgy
Instantaneous Melt Integration: The 0-1mm ultra-fine distribution ensures immediate dissociation and reaction upon contact with molten metal.
Maximum Silicon Recovery: Achieve up to 96% Silicon yield with a high-purity 90% SiC concentrate, minimizing costly alloy waste.
Enhanced Slag Foaming: Accelerates the formation of stable foamy slag in EAF operations, protecting refractories and improving energy efficiency.
Eliminate Gas Defects: Aggressively scavenges dissolved oxygen to prevent CO-related pinholes and nitrogen-induced brittleness.
Direct Factory Sourcing: Procurement from ZhenAn guarantees batch-to-batch chemical stability and ISO-certified quality for global steel mills.
The Advantage of Micro-Granular SiC 90%
In high-velocity steelmaking and precision foundry lines, the reaction time is a critical KPI. ZhenAn's 0-1mm Silicon Carbide Powder provides a massive active surface area compared to traditional lumps. This high-purity deoxidizer is specifically designed for injection systems and ladle trimming where "time-to-chemistry" is measured in seconds.
The metallurgical pathway is highly efficient:
SiC + 3[O] → SiO₂ + CO↑
The micro-bubbles generated by this reaction provide a secondary "flotation" effect, lifting microscopic non-metallic inclusions to the slag layer, resulting in ultra-clean steel.
Key Applications & Performance Metrics
Ladle Metallurgy & Trimming: For mills producing automotive or aerospace-grade alloys, the 0-1mm powder is the ideal trimming agent. It allows for precise Carbon and Silicon adjustments during the final stages of the heat without the risk of undissolved material.
Cored-Wire Manufacturing: Due to its excellent flowability and consistent 90% purity, our powder is the industry standard for filling deoxidizing cored wires. This ensures a stable, deep-injection delivery of SiC into the heart of the ladle.
Induction Furnace Deoxidation: In small-to-medium induction furnaces, the 0-1mm powder can be mixed with the charge or added as a top-dressing to rapidly "kill" the slag, preventing the oxidation of expensive alloying elements like Chromium or Manganese.

Precision Screening: Our 0-1mm product is triple-screened to ensure a consistent PSD (Particle Size Distribution), preventing "oversize" contamination in automated dosing systems.
Low-Nitrogen Chemistry: Our high-purity SiC is processed to maintain ultra-low Nitrogen levels, making it the preferred choice for producing deep-drawing quality (DDQ) steels.
Global Supply Continuity: With a 150,000-ton annual output capacity, ZhenAn provides a stable buffer against market price fluctuations and supply chain disruptions.
FAQ: Frequently Asked Questions
Why use 0-1mm powder instead of 1-10mm granules?
Powder is designed for speed. The 0-1mm size has roughly 10 times the reactive surface area of larger granules, making it the best choice for ladle additions where the alloy needs to be fully absorbed before the caster.
Does the fine size (0-1mm) lead to significant dust loss?
ZhenAn utilizes a specialized "micro-granulation" process that minimizes ultra-fine dust. This ensures the powder sinks through the slag layer effectively rather than being sucked into the furnace's environmental extraction system.
Is this powder suitable for producing Spheroidal Graphite (SG) iron?
Yes. It is an excellent pre-conditioner for ductile iron base metal. It ensures the melt is fully deoxidized before the Magnesium treatment, which significantly increases the nodularity and reduces the required Mg dosage.
How does the carbon recovery of SiC powder compare to graphite?
Because the Carbon in SiC is chemically bonded, it is much more stable than "free" graphite. In a molten bath, the SiC Carbon is absorbed more predictably, leading to a tighter carbon hit-rate and fewer chemistry rejections.
What is the standard packaging for export?
We typically provide 1.0mt or 1.25mt waterproof jumbo bags. For cored-wire manufacturers, we can also provide 25kg small bags palletized for easier handling and dosing.
Does ZhenAn provide third-party testing for chemical purity?
Absolutely. While we conduct rigorous internal lab testing for every lot, we also partner with SGS, Bureau Veritas, and TUV to provide independent verification of our SiC content and size distribution upon client request.
