Alumina Powder
Calcined and alpha alumina for ceramics, refractories, coatings and polishing — bought directly from major producers in Zibo.
Overview
Alumina powder is not made on our own lines, and we say so plainly. Zibo is one of China's alumina centres: we buy calcined and alpha alumina directly and in volume from major producers, check the documents, and quote one clear EXW price. You get producer material without another trading layer in between.
Applications
- Advanced and technical ceramics
- Refractories and high-temperature linings
- Coatings and surface treatment
- Polishing and abrasive applications

Frequently asked
Why buy a sourced product from you?
One accountable contact, producer-level pricing from volume buying, and documents checked before shipment — instead of chasing a producer's sales desk yourself.
Can you hit our exact specification?
Send your target values (Al₂O₃, Na₂O, D50) or the grade you buy today; we will confirm against producer datasheets before quoting.
How is freight handled?
We quote EXW. Ocean freight changes daily, so it is calculated for your specific order and destination — no inflated bundled price.
Request a quotation
To confirm the right grade, it helps to send: Application, target specification (Al₂O₃, Na₂O, D50) or current grade, and estimated volume.
