99% Silicon Metal Powder 20-120 Mesh

 

We supply 99% silicon metal powder in 20-120 mesh for chemical engineering and other industrial processing requirements.

The current specification contains at least 99.0% Si, with Fe controlled to ≤0.4%, Al ≤0.4% and Ca ≤0.1%.

When you purchase silicon metal powder, purity and particle size should be confirmed together. A material may meet the required Si percentage but still be unsuitable if the powder size, impurity limits or batch consistency do not match your process.

If your production has tighter Fe, Al or Ca limits, send us the required chemistry before quotation so we can check the available specification against your actual requirement.

 

99% Silicon Metal Powder, 20-120 Mesh

 

 

Product	Particle Size	Si ≥	Fe ≤	Al ≤	Ca ≤
Silicon Metal Powder for Chemical Engineering	20-120 Mesh	99.0%	0.4%	0.4%	0.1%

For batch acceptance, we recommend confirming the agreed Si minimum, Fe/Al/Ca maximums and particle-size requirement in the quotation and batch documentation.

If other elements are important to your process, list those impurity limits separately rather than assuming that a general 99% Si specification controls every trace element.

 

 

The 20-120 mesh designation describes the physical particle-size range, while 99% Si describes the Chemical Composition.

You should confirm both parameters separately because particle size can affect:

• mixing and dispersion;
• feeding behavior;
• reaction rate in chemical processing;
• powder handling;
• dust generation;
• downstream formulation consistency.

If your process requires a narrower mesh distribution, state the required range and sieve acceptance method in the RFQ.

 

 

The current 20-120 mesh specification is positioned mainly for chemical engineering and industrial processing.

You can evaluate silicon metal powder where controlled silicon input and fine-particle handling are required, including silicon-based chemical processing and other industrial formulations.

Before use, confirm:

• required Si purity;
• Fe, Al and Ca limits;
• particle-size distribution;
• reaction or processing conditions;
• powder feeding method;
• required batch inspection values.

If you are sourcing material for photovoltaic, semiconductor or another ultra-high-purity process, send us the complete incoming-material specification first. A general 99% industrial silicon powder should not automatically be treated as electronic-grade or solar-grade silicon.

 

 

The impurity profile can be just as important as the headline silicon percentage.

Iron in Silicon Metal Powder

The current specification lists Fe ≤0.4%. If iron affects your downstream chemistry, state a tighter maximum directly in the purchase specification.

Aluminum in Silicon Metal Powder

The listed Al limit is ≤0.4%. We recommend checking the actual batch result when aluminum content is important to your process.

Calcium in Silicon Metal Powder

The current specification controls Ca at ≤0.1%. If calcium affects reaction behavior or final product chemistry, confirm the maximum accepted value before production.

 

 

For industrial powder orders, we recommend aligning the purchase specification with the final inspection requirements before shipment.

The main items you can confirm with us include:

• Si minimum;
• Fe, Al and Ca maximums;
• 20-120 mesh particle-size requirement;
• additional impurity limits;
• batch identification;
• required COA or inspection documents.

If you have your own testing method or incoming-inspection standard, send it before order confirmation so we can check whether it can be aligned with the supply specification.

 

 

 

 

 

You can discuss silicon powder chemistry, particle size, sample requirements, inspection documents and export arrangements directly with us before order confirmation.

 

 

RFQ Item	What You Should Provide
Si Purity	99% or your required minimum Si
Particle Size	20-120 mesh or your required mesh range
Impurities	Required Fe, Al, Ca and other impurity limits
Application	Chemical engineering or other industrial process
Quantity	Trial or bulk order quantity
Packing	Your required bag weight or export packing format
Documents	COA or other required inspection / export documents
Destination	Destination port or delivery location

Because packing and delivery details are not fixed on the current product specification, we will confirm them according to your quantity, destination and handling requirements.

 

 

Q1: What is the silicon content of this metal powder?
The current specification lists Si at ≥99.0%.

Q2: What particle size is available?
The current listed specification is 20-120 mesh. If you need a different or narrower size distribution, send us the required mesh range.

Q3: What are the Fe, Al and Ca limits?
The listed maximums are Fe ≤0.4%, Al ≤0.4% and Ca ≤0.1%.

Q4: Can I use this silicon powder for chemical engineering?
Yes. The current specification is positioned for chemical-engineering and other industrial processing requirements.

Q5: Is this silicon powder semiconductor grade?
No such semiconductor-grade specification is established by the current 99% Si product data. If your process requires electronic or photovoltaic feedstock, send us the complete purity and trace-element specification first.

Q6: Can you provide a different mesh size?
Send us the required particle-size range and we will confirm the available processing option before quotation.

Q7: Can you provide a sample?
Send us the required chemistry, mesh size and application so we can confirm the appropriate sample arrangement.

Q8: What information should I send for pricing?
Send the required Si purity, Fe/Al/Ca limits, particle size, quantity, packing, destination and document requirements.

 

 

 

We can confirm silicon metal powder chemistry, mesh size, inspection requirements, packing and export documents according to your agreed specification.
