Silicon Supplier in Malaysia
- Also known as
- Si
Silicon supplier in Malaysia for metallurgical, solar, semiconductor, refractory and chemical-conversion requirements. This page covers elemental silicon, identified by the symbol Si and CAS 7440-21-3, not silica, a silicate, silicon carbide or a silicone polymer.
Metallurgical silicon is commonly purchased as lumps, crushed pieces or granules for alloying and chemical conversion. Solar and electronic grades use tighter trace-impurity controls as polycrystalline feedstock, while elemental silicon powder is selected by purity and particle-size requirements.
Foundries and metal producers use silicon in alloys, photovoltaic and semiconductor processors use it for crystal and wafer production, and refractory makers specify powder for selected formulations. Each route requires a distinct grade and should not be substituted with a silica-based material.
Send the required grade, purity, trace-element limits, physical form, particle size, quantity and delivery location with your enquiry. Availability, packing, documentation, delivery timing and silicon price are confirmed with a quotation carrying a stated validity period.

Silicon grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Metallurgical-grade silicon | lumps, granules or crushed material | — | Alloying, foundry and chemical conversion where the buyer specifies elemental silicon purity, trace-element limits and the required lump or granule size. | Confirm the required pack format with the quotation. |
| Solar-grade polysilicon | polycrystalline chunks or granules | — | Photovoltaic feedstock that requires a tightly controlled elemental silicon grade and trace-impurity specification for downstream crystal production. | Confirm the required pack format with the quotation. |
| Electronic-grade silicon | high-purity polycrystalline feedstock in the form specified by the processor | — | Semiconductor crystal and wafer production where the buyer defines purity, dopant and electrical-property requirements. | Confirm the required pack format with the quotation. |
| Silicon powder | grey to dark grey powder in a specified particle-size range | — | Refractory, alloying and specialised materials processes that require elemental silicon powder rather than silica, silicon carbide or a silicone. | Confirm the required pack format with the quotation. |

Safety and handling
Keep silicon forms sealed, dry and protected from contamination. Fine powder should be handled using the safety information and controls specified for the quoted particle form.
Common questions about Silicon
Is silicon the same as silica?
No. Silicon is the element Si with CAS 7440-21-3. Silica is silicon dioxide, a separate compound used in sand, flour, gel and fumed-silica products. State elemental silicon when that is what the specification requires.
Is silicon the same as silicone?
No. Silicon is an element. Silicones are manufactured polymers containing silicon, oxygen and organic groups and are sold as products such as silicone oil, emulsion or rubber. They are not alternate names for elemental silicon.
Which grades of elemental silicon can be requested?
Enquiries may cover metallurgical-grade silicon, solar-grade polysilicon, electronic-grade silicon and silicon powder. Each has different purity, trace-impurity and physical-form requirements.
What forms of silicon are used in industrial purchasing?
Lumps and granules are common for metallurgical conversion, polycrystalline chunks serve solar and electronic processing, and powder is specified for selected refractory or materials applications.
What specifications should accompany a silicon enquiry?
Provide the grade, silicon purity, trace-metal, boron and phosphorus limits, plus lump size or powder particle size. Solar and electronic users should include the applicable dopant and electrical-property requirements.
How is silicon price confirmed?
Price depends on grade, purity, trace-impurity limits, form, particle size, quantity, packing and delivery requirement. The quotation therefore carries a stated validity period.
