Patreon Preview - Make Potassium Nitrate and Sodium Nitrate Revisited with Calcium Nitrate
Added 2024-05-11 06:34:51 +0000 UTCAs usual a preview. I'm taking a short break from the Oleum work while i fix the ceramic hotplate. I thought i revisit one of the mainstays of amateur chemistry and update it for the modern realities of nitrate procurement.
Let me know what you think and if there are any questions, or other methods to cover.
I'll see if i can post this next week.

Yes agreed, the question is can you produce what you want without it costing too much

This was often confused with CAN (Calcium Ammonium Nitrate) There are two grades of CAN available in the UK from Yara, greenhouse grade for Fertigation and field grade. The field grade is contaminated with Latex as it must have been used in some Latex processiong plant before being bagged for fertiliser. I have also recently found a source of Calcium nitrate all be it in solution from builders merchants as "Chloride free accelerator" for concrete. Yara the world largest producers of Nitrates sell a product "NitCal" that is a mixture of Calcium and Potassium Nitrates but I am yet to find it in 25kg sacks. https://www.yara.com/industrial-nitrogen/concrete-additives/concrete-setting-accelerator/ Material Safety data sheets are your friend when it comes to finding sources
