How to distinguish the name :Calcium Nitrate ; Calcium Ammonium Nitrate (CAN) and Granular CAN ?

Sometimes people said Calcium Nitrate,but exactly they mean Calcium Ammonium Nitrate (CAN) .

Very confused. anyone know ?

Thanks

Calcium Nitrate is simply Ca(NO3)2 eventually with water of crystalisation.

Calcium Ammonium Nitrate (CAN) or Granular CAN is simply a mix of NH4NO3 and Ca(NO3)2 (eventually with water of crystalisation)

I guess that you may find the difference on the label by the % nitrogen (N) vs amount of Ca...
CAN must be richer at N since NH4NO3 contains 2 N atoms per molecule...

Of course when you say CAN I think of Cerric Ammonium Nitrate which in my circles is the most common use for that abbreviation. Unfortunately you have to sometimes infer the identity of a chemical from the context but it SHOULD be identified somewhere before the acronym is employed. In a book this might be just before the introduction in a table or it could be interwoven in the text.

Just not common enough, apparently? :D

CAN can also be AN mixed with Lime

ammonium nitrate-based fertilisers with dolomite, limestone, and/or calcium carbonate

http://www.yara.co.nz/crop-nutrition/products/yarabela/7660-...

usually around 70-<80% AN to avoid additional regulations around ammonium nitrate storage in some countries.

NPK wont help as the ratio can vary depending on brand.

If in doubt find the MSDS

Add sodium carbonate to its solution to see if CaCO3 precipitates

I have come CalNit 15.5-0-0 and IDK what it is.. It is manufactured by Yaris. When dissolved in water, filtered, then boiled to evap an ammonia smell eminates from it. After a complete dissolve and recrystalization to anhydrous form, a VERY pungent ammonia smell is present when KOH is added to it. If the 2 compounds are mixed dry, it will hiss, get hot and emit very strong ammonia smell.

So, I don't know if this is truly Ca(NO3)2 or what.

Ammonium nitrate releases small amounts of ammonia in boiling water and KOH being very hygroscopic reacts because it retains moisture!

Yara, a major international company that likely wouldn't exist were it not for the Birkeland Eyde NO2 generator!

Their UnikaKali fert. is KNO3, BTW!
