Description
- Potassium nitrate is meticulously sourced and refined to ensure the highest purity.
- Laboratory Grade Purity makes this ideal for precisision and high quality control in your experiments and formulations.
- Product consistency is ultra fine sand like granules, which is ideal as the high surface area allows for fast, efficient and complete chemical reactions to occur.
- This product is laboratory grade, meaning that it conforms to the high quality standards for laboratory grade chemicals.
- Potassium nitrate is sometimes used in gold refining as part of the process known as cupellation. Cupellation is a refining process in metallurgy where ores or alloyed metals are treated with a reagent such as lead oxide or potassium nitrate in a high-temperature furnace to separate noble metals like gold and silver from base metals.When potassium nitrate is used in cupellation, it helps oxidize any base metals present in the alloy, leaving only the noble metals behind. This process helps purify the gold and separate it from any impurities or base metals that may be present.Overall, potassium nitrate can be used as an oxidizing agent in gold refining to help separate and purify the noble metals from base metals in the alloy.
