Need help with AgNO2 crystal

Hi Heiko4

I was quite impressed with the quality of the sample in your AgNO2 crystal contribution. https://commons.wikimedia.org/wiki/File:Silbernitrit.jpg#file

It quite closely relates to my work, and I would like to learn more about the sample preparation or the source. Could you please help me with it?

Thanks for your time and help.

Hallo Sushi86, es handelt sich um eine Fällung. In die Silbernitratlösung wurde ein Körnchen Natriumnitrit geschoben. Alles mikroskopisch auf dem Objektträger. Viele Grüße, Heiko — Preceding unsigned comment added by Heiko4 (talk • contribs) 23:12, 26 November 2019 (UTC)

AgNO2 figure

Hi Heiko

Hope everything is well with you. We were very impressed with the image of AgNO2 crystal that you produced. I want to cite your publication/picture in my research and was wondering if I could do it? If yes, please direct me to the required reference.

Thank you so much!
