Sillimanite Supplier in Malaysia
- Also known as
- Al2SiO5
Sillimanite is an aluminosilicate mineral supplied for Malaysian refractory, ceramic, foundry and high-temperature manufacturing enquiries. Buyers normally qualify it by mineral composition, alumina and silica basis, iron content, loss on ignition and particle size.
Commercial requirements may cover sized refractory grains, ceramic-grade powder or fine-milled material. Mesh, top size and particle-size distribution should be stated because they influence packing density, mixing and finished-product performance.
Sillimanite is used in refractory bricks, castables, kiln furniture, foundry products and specialty ceramic formulations. It is a distinct Al2SiO5 mineral and should not be treated as interchangeable with alumina, silica, kaolin or feldspar.
Send the required sillimanite grade, chemical limits, particle size, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed for the quoted mineral specification.
- Grade
- refractory, ceramic, milled mineral
- Appearance
- grey, brown or pale granular mineral and powder
Sillimanite 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 |
|---|---|---|---|---|
| Refractory-grade sillimanite | sized mineral grains or powder | — | Refractory brick, castable and shaped-product formulations requiring an aluminosilicate raw material. | Confirm the required dry bulk or bag format with the quotation. |
| Ceramic-grade sillimanite | milled mineral powder | — | Ceramic bodies and kiln products where alumina, silica, iron and particle-size limits are controlled. | Confirm the required dry pack format with the quotation. |
| Fine-milled sillimanite | fine mineral powder | — | Fine ceramic, investment-casting and specialty mineral formulations requiring a defined particle distribution. | Confirm the required dry pack format with the quotation. |

Common questions about sillimanite
What is sillimanite used for industrially?
It is used mainly as an aluminosilicate raw material in refractories, ceramics, foundry products and other high-temperature applications.
Which sillimanite specifications should be provided?
State the required alumina, silica, iron oxide, moisture, loss on ignition and particle-size or mesh limits.
Can fine-milled sillimanite be requested?
Yes. Provide the target particle-size distribution, top-size limit and application so a suitable milled grade can be assessed.
Is sillimanite the same as alumina or silica?
No. Sillimanite is a distinct aluminosilicate mineral with the formula Al2SiO5, not a single-oxide raw material.
How are packing and batch documents confirmed?
Include the preferred dry pack format and required chemical or particle-size documents. Availability is confirmed with the quotation.
