Technical Grade Silicon Metal 1101
Product Overview
Technical Grade Silicon Metal 1101 is a high-purity metallurgical material primary used in premium aluminum alloy manufacturing, silicone chemical synthesis, and anti-refractory industries. By enforcing rigorous chemical control during the smelting process, we ensure minimal trace impurities, delivering unparalleled thermal conductivity and structural stability to your end products.
Key Advantages of Our 1101 Grade
Ultra-Low Impurity Window: Ferrous (Fe ≤ 0.1%) and Aluminum (Al ≤ 0.1%) elements are strictly capped to eliminate the risk of batch contamination in high-end alloy casting.
Uniform Sizing, Minimal Slag: Available in standard 10–100mm lumps or custom-ground mesh sizes, ensuring high dissolution rates and uniform heat absorption in smelting furnaces.
Superior Chemical Stability: High active Silicon content (Si ≥ 99.5%) significantly enhances anti-oxidation properties and extends the lifespan of the resulting refractory materials.

Main Applications
1. Silicone & Siloxane Synthesis
Premium-grade raw material optimized for silicone oils, elastomers, industrial adhesives, and sealants.
Minimizing trace elements drastically improves polymerization rates and batch reaction stability.
2. High-Performance Aluminum Alloys
Extensively used in automotive, aerospace, and high-precision industrial castings.
Noticeably enhances molten alloy fluidity, mechanical strength, and oxidation resistance.
3. Advanced Metallurgical Processing
Functions as an exceptional, high-efficiency reducing agent in high-temperature submerged arc smelting.
Promotes the production of cleaner steels by lowering uncontained inclusion formations.
4. Technical-Grade Semiconductor Feedstock
Tailored for chemical vapor deposition (CVD) processes requiring non-electronic grade specifications.
Essential precursor for solar-grade polysilicon and cutting-edge composite material synthesis.
FAQ
Q1: How can we get an accurate and up-to-date price quote for Silicon Metal 1101?
A: Silicon metal prices fluctuate daily based on global raw material and energy costs. Please click the [Inquire Now] button or email us with your required monthly volume, target particle size, and destination port (FOB/CIF). Our team will provide a firm quote within 2 hours.
Q2: Do you support independent third-party inspections (SGS / BV) before shipment?
A: Yes, 100%. We completely welcome internationally recognized testing agencies such as SGS, Bureau Veritas (BV), or Intertek to perform independent chemical analysis, quantity verification, and container loading supervision at the port of departure.
Q3: What is your standard policy on providing pre-shipment samples?
A: We gladly provide free samples of Silicon Metal 1101 along with our latest factory COA (Certificate of Analysis). Buyers only need to cover the international courier/express cost, which will be fully refunded upon our first official contract order.
Q4: What are your standard payment terms for bulk container shipments?
A: Our standard terms are T/T (30% advance deposit, 70% balance payable against the scan copy of the Bill of Lading) or 100% Irrevocable L/C at sight. We are also open to flexible payment structures for verified, long-term contract partners.
