Description
ZhenAn's high-purity Silicon Carbide (SiC) Grain (available in 90% and 88% grades) is a premium deoxidizer and alloying agent specifically engineered for the precision casting and metallurgical industries. By providing a stable source of silicon and carbon, it ensures superior melt quality and precise chemical control for high-performance foundries.
Key Advantages of ZhenAn Silicon Carbide
  • Superior Deoxidation Efficiency: Effectively removes dissolved oxygen from molten metal, preventing gas porosity and improving melt fluidity
  • Low Impurity Profile: Strictly monitored for trace elements like aluminum and sulfur, ensuring integrity of complex castings
  • Enhanced Nucleation: Acts as potent inoculant, promoting fine-grained structures and improving mechanical properties
  • Cost-Effective Performance: Provides stable recovery rate compared to traditional ferrosilicon, reducing production costs
  • ISO Certified Quality: Produced under rigorous ISO 9001:2015 standards, guaranteeing batch-to-batch consistency

Industrial Applications
Our Silicon Carbide Grain is indispensable across various sectors of the metalworking industry:
  • Investment & Precision Casting: Ideal for stainless steel and alloy steel castings where high purity and surface finish are critical
  • Gray & Ductile Iron Production: Used as carbon raiser and deoxidizer to improve graphite morphology and reduce chill
  • Steelmaking Deoxidation: Replaces portion of Ferrosilicon and Carburizer in electric arc furnaces to reduce energy consumption
  • Refractory Manufacturing: Utilized as raw material for high-temperature crucibles and kiln furniture due to excellent thermal properties
Packaging & Delivery Information
  • Physical State: Available in granular (grain) or lump form, processed through precision crushing and screening
  • Packaging: Standard 1-metric ton (1000kg) big bags, or 25kg small bags palletized and shrink-wrapped for moisture protection
  • Logistics: Strategically located near major shipping ports for rapid international delivery with Certificate of Analysis included
Frequently Asked Questions
What is the benefit of using SiC over Ferrosilicon?
SiC introduces both Silicon and Carbon simultaneously and reacts exothermically, which helps maintain melt temperature and reduces electricity costs.
Can I customize the grain size?
Yes, ZhenAn provides custom screening. Common sizes include 0-10mm, 1-5mm, and 200 mesh powder.
How does SiC affect the slag in my furnace?
It creates a more fluid slag, making it easier to remove and protecting the furnace lining from premature erosion.
Is your material tested for moisture?
Absolutely. We ensure all grain is stored in dry environments and tested for low moisture content to prevent hydrogen pickup in the melt.
What is your minimum order quantity (MOQ)?
Our standard MOQ is 20-25 tons (one full container), but we can discuss smaller trial orders for specific casting projects.
Do you provide third-party inspection?
Yes, we support SGS, BV, or any other third-party inspection required by the client prior to shipping.
