Where can I buy clay minerals for experiments? I am looking for kyanite, andalusite, sillimanite, allophane, hematite, goethite, gibbsite, montmorillonite, kaolinite, etc. I need pure reference minerals for chemical experiments.
Thank you Dr. Aurelio, but I need clay size reference materials, not the minerals. I still need help. I would appreciate the help of specialists!!
I suggest to visit the wordsci company at this link

Or you can look at ebay and amazoon
Thank you for the help Drs. Nasir and Towe. Then I will look for some clay size minerals and some powered minerals. If anyone knows more sources, it would be very much appreciated.
Thank you again Dr. Aurelio. The information you all provided was very helpful. I will try to find and buy some materials for my studies.
Hi, Giuliano
Do you find your clay minerals? I also have the same questions with you.
Dear Huaguang Wang, I followed suggestion above from Aurelio Sanz Arranz. I also found some standards to buy at: http://www.lgcstandards.com/
Hematite and goethite are available from
http://bayferrox.com/en/home-bayferrox/
e.g. hematite http://bayferrox.com/en/products-applications-bfx/product-search/bayferrox-110/
The question is 3 years old, but close to mine:
Does anyone know where I can find pure illite, smectite and vermiculite to buy? Prefarably in Europe. 1 g would be enough.
Hey Jonathon, You can check of the CMS repository. It's in the USA but they ship
Erin Gibbons Right now the CMS repository is lacking both pure illite and vermiculite.
