What This Market Note Covers
This article reviews the indicative spot price levels for industrial silicon metal powder (also called silicon metal powder or metallic silicon powder) published in the original market note dated August 5, and places them in the context of the supply, demand and cost factors that drive the market. Silicon metal powder is widely used in aluminum alloys, refractory materials, organic silicon and chemical applications; the 16-200 mesh size range is one of the most common commercial specifications.
Indicative Spot Price Levels
The quotations below are reproduced from the original market note dated August 5 (the year was not stated in the source) and are expressed in RMB per ton. They should be treated as historical reference levels, not as current tradable prices. Actual transaction prices vary with grade, particle size distribution, order volume, payment terms and logistics.
| Specification | Quotation (RMB/ton) | Change | Sold Price (RMB/ton) | Change |
|---|---|---|---|---|
| 553 (16-200 mesh) | 10,600-10,900 | -- | 10,000-10,600 | -- |
| Si ≥ 99% (16-200 mesh) | 10,700-11,000 | -- | 10,100-10,600 | -- |
The gap between quotation and sold price reflects typical negotiation room in the spot market. Since the date of the original note, prices have continued to move with the balance between production and downstream demand; the table should be read as a snapshot, not as a forecast.
Supply and Demand Drivers
China is the largest producer of silicon metal and silicon metal powder. Production is concentrated in hydropower-rich regions such as Yunnan and Sichuan, which means output follows the seasonal availability of hydroelectric power: capacity utilization typically rises during the wet season and falls when power supply tightens. On the demand side, the main consumers are aluminum alloy producers (silicon raises fluidity and casting quality), polysilicon manufacturers for photovoltaics, organic silicon producers, refractories and the chemical industry. When downstream sectors operate at high rates, powder demand strengthens and spot prices firm.
Cost Structure and Price Influencing Factors
Electricity is the single largest cost component of silicon metal production, so changes in power tariffs and power curtailment directly affect supply cost. Other key inputs are quartz (silica) and carbon reductants such as coal, coke and charcoal. Beyond production cost, spot prices are influenced by producer inventories, downstream restocking cycles, export demand, logistics costs and seasonal expectations. Buyers should monitor these factors rather than rely on a single quoted level.
Procurement Guidance for Buyers
Confirm the required grade: "553" refers to a common industrial silicon grade, while "Si ≥ 99%" specifies a minimum silicon content; verify the full specification with the supplier.
Specify the particle size distribution (for example 16-200 mesh) and check the actual sieve analysis on delivery.
Compare quoted and transacted prices across several suppliers, and note that the quoted price is a starting point, not a firm offer.
Request a certificate of analysis for silicon content and key impurities on every lot.
Plan purchases against your consumption schedule; buying during periods of seasonal oversupply can reduce cost, while supply can tighten during power-constrained periods.
Frequently Asked Questions
Q1: What does the specification "553" mean in silicon metal powder?
"553" is a common industrial silicon grade designation indicating the permitted maximum levels of iron, aluminum and calcium impurities (roughly 0.5%, 0.5% and 0.3% respectively in the conventional reading).
Q2: What is the difference between quotation price and sold price?
The quotation is the seller's published offer level, while the sold price reflects the range at which transactions are actually concluded; a gap between them is normal in the spot market.
Q3: What is silicon metal powder used for?
It is used in aluminum alloys, refractories, organic silicon, chemical products, and as a raw material in photovoltaic and electronics-related processes.
Q4: What mesh size should I order?
16-200 mesh is a common commercial range; the right size depends on your process - finer powder reacts faster but is more difficult to handle, while coarser material feeds more easily.
Q5: Are the prices in this article current?
No. The figures come from a market note dated August 5 and are historical reference levels; current quotes should be obtained directly from suppliers.
Q6: What drives silicon metal powder price changes?
Electricity costs, hydropower seasonality, quartz and reductant prices, producer inventories, downstream demand and export conditions are the main drivers.
