Alisha Sharma Alisha, Most of it comes in solid shapes, rods, tubes or sheets. Do want a powder and will mold it yourself.

Also, you can to a search and click on the "shopping" tab to find vendors your area.

Thank you for your response Lee Clawson .

Does molding affect its property?

Alisha Sharma -- Alisha, in general there should be minimal change. However, the quality of the alumina, the use of additives to make and or release the product frrom a mold, the physcial uniformity of the part can introduce variations. You should buy from a known source and if necessary a scientific part supplier. Call people who make or use alumina for similar use and ask where they obtain the product. --- If you're not experienced in molding buy pre-made parts.
