Dear all,
for synthesis of Ba-Hollandite (BaMn8O16) described in: Cheng, S., Lin, J. T., Ocelli, M. L., & Robson, H. E. (1992). Expanded Clays and Microporous Solids (p.335 & 337), I need Ba-Permanganite (Ba(MnO4)2).
Unfortunately, this seems very hard to purchase, at least no "typical" supplier offers it. Has anyone a suggestion, where to get some small amounts (~ 10-15 g) of Ba(MnO4)2 with a purity of >99% ?
Or: Does anyone know another well working synthesis protocol yielding pure BaMn8O16? A natural speciment would work too, but I haven´t found any that is chemically homogeneous enough.
So, I am looking forward to your suggestions and ideas!
Thank you very much,
Teresa
Dear Dr. Teresa Zahoransky,

Please also consider the product safety data sheets.
Best regards, Pierluigi Traverso
Dear Mr. Traverso,
thank you very much for your kind help. Unfortunately, all suggested suppliers there also seem to not sell the product anymore - yet, I send some inquiries to make sure.
Thank you for your suggestions,
Teresa Zahoransky
You can request from Sigma Aldrich, or check bristolscientific, or ask [email protected].
Dear Mr Egbujor,
thank you very much for your suggestion. I will ask at bristolscientific!
Yours sincerely,

Dear Teresa Zahoransky, just in case that you consider preparing barium permanganate yourself, please find attached a description of the synthetic method. The preparation is also described in the Brauer Handbook of preparative Inorganic Chemistry.

Dear Mr. Elemann,
thank you very much for suggesting the method of Schlessinger (1962).
Yours sincerely,
Teresa Zahoransky
Dear Teresa Zahoransky I hope it was helpful. Just one minor remark: It is a good practice in RG to recommend answers given by other RG members to help you solve a problem.
