Typical Applications of silicon carbide 80-90%
1) Metallurgy (Deoxidizer / Additive)
SiC can help reduce oxidation and support process efficiency in certain metallurgical operations. The 80–90% grade is often chosen for cost-performance balance.
Suitable for: steelmaking / foundry / ferroalloy / specific process
Notes: Tell us your furnace type and target chemistry; we can recommend an appropriate grade and size.
2) Refractory / Castables
SiC is widely used in refractory mixes to improve wear resistance and thermal performance depending on formulation.
Suitable for: refractory castables / ramming mix / kiln furniture / etc.
Notes: Share your mix design or performance target; we can propose size and grade options.
3) Other Industrial Uses
Abrasive and wear-resistant systems (depending on size/grade)
Special industrial ceramics (application-dependent)
If you tell us your end-use, we can confirm whether 0–10 mm is optimal or recommend a tighter fraction.
FAQ
Q1: Is HS code 284920 applicable to this product?
A1:Yes. This product is Silicon Carbide (SiC) and is commonly declared under HS Code 284920. Final customs classification may vary by destination country requirements; we can provide standard export documents accordingly.
Q2: What does "80–90% SiC" mean? Can you supply a tighter grade?
A2:It indicates the SiC content range. We can offer tighter ranges (for example, 80–85% or 85–90%) depending on availability and your application requirements. Please request a batch COA for confirmation.
Q3: How is the 0–10 mm size controlled?
A3:We control size through sieving/grading. Tighter fractions (e.g., 1–3 mm, 3–5 mm, 5–10 mm) are available if you need more consistent feeding behavior.
Q4: Can you provide COA for each batch?
A4:Yes. COA per batch is available, and we can also support third-party testing if required.
Q5: What impurities are most important for buyers?
A5:Typically Fe₂O₃, SiO₂, free carbon, and moisture are key items. Tell us your process and spec limits, and we will confirm suitability.
Q6: What is your MOQ and lead time?
A6:MOQ is 1ton and lead time is typically 7-15 days depending on quantity and packaging.
Q7: What packaging do you offer?
A7:Standard packaging includes 25 kg bags and 1 MT jumbo bags, with pallet options. Custom packaging is possible.
Q8: Can you ship to the USA and provide export documents?
A8:Yes. We can ship to the USA and provide standard export documents such as commercial invoice, packing list, COA, and SDS/MSDS.
