can anyone tell me some uses of this chemical or easy ways of obtaining it, is it a "watched chem"?

i don't know why you would want it(assuming your making meth), it's used in making safety matches, not the matches you can extract red phosporus from. But if you still want it it isn't watched or controlled, and im sure you can find a chemical supplier to sell it

Here's what my search turned up....



Applications

For applications which are sensitive to moisture or where a source of potassium is required for the end use, potassium dichromate is used in preference to sodium dichromate.



Elementis is the only manufacturer to use chromic acid as the feedstock for potassium dichromate production. This process results in high quality products distinguished by low chloride values.



Potassium dichromate is used in the manufacture of the following products:

-catalyst for the production of chromium metal

-photographic engraving and lithographic chemicals

-pyrotechnics and safety matches analytical standard



This product is supplied as a bright orange crystal in 50kg packages.
