Silicon carbide price

Silicon Carbide prices are primarily driven by purity levels (SiC content) and particle size distribution. For industrial abrasives, a purity of 98% or higher is standard, while metallurgical grade may be lower. You must specify whether you require Black Silicon Carbide (typically for abrasives and refractories) or Green Silicon Carbide (higher purity, used for electronics and precision grinding), as the latter commands a significant price premium. Additionally, ensure the Grit Size (FEPA or JIS standards) aligns with your specific application to avoid processing surcharges.

The intended use dictates the required quality tier. For refractory applications, focus on thermal shock resistance and bulk density; for semiconductor manufacturing, the focus shifts to ultra-high purity and crystal integrity, which exponentially increases the price. To optimize costs, buyers should match the chemical composition (Free Carbon and Iron content) strictly to their process needs—over-specifying purity can lead to unnecessary expenditure of 20-40%.

Suppliers should provide Material Safety Data Sheets (MSDS) and comply with ISO 9001 for quality management. For international trade, verify adherence to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) if exporting to Europe. Ensure the supplier provides a Certificate of Analysis (COA) for every batch, specifically detailing the chemical analysis and sieve analysis to guarantee consistency in production.

Silicon Carbide is energy-intensive to produce; therefore, prices fluctuate with electricity costs and raw material (petroleum coke and silica) availability. To secure stable pricing, consider long-term framework agreements or volume-based contracts. On platforms like Made-in-China.com, you can identify verified manufacturers who offer tiered pricing structures, allowing you to lock in rates for bulk shipments and reduce exposure to spot market spikes.

Due to its high density and abrasive nature, Silicon Carbide is typically shipped in 1-ton Jumbo Bags (FIBC) or 25kg multi-layer paper bags on pallets. Ensure the packaging is moisture-proof to prevent clumping. When negotiating shipping, clarify the Incoterms (e.g., FOB or CIF); given the weight-to-volume ratio, sea freight is the most economical method. Always request photos of the loading process to ensure the integrity of the bags and pallets before the vessel departs.

Prioritize suppliers on Made-in-China.com that have undergone on-site audits by third-party agencies (like SGS or TÜV Rheinland). Use Secured Trading Services to protect your payments until the goods pass inspection. For first-time orders, it is highly recommended to appoint a third-party inspector to conduct a Pre-Shipment Inspection (PSI) to verify that the grit size and purity match the agreed-upon samples.
