Potassium Nitrate Technical Grade KNO3


Technical Grade Potassium Nitrate Crystals

Priced per pound - 5 Lb Minimum





We were the first supplier to offer technical grade to the hobby community in 2013. Once the word spread about it's purity and superiority, other suppliers jumped on the bandwagon claiming their KNO3 was also "Technical Grade". Hmm....

Technical Grade KNO3 has half the insolubles found in the Greenhouse Grade. It's produced by the manufacturer's technical division and marketed specifically for;

  • Glass (cathode ray tubes, lead crystal, heat treating)
  • Pyrotechnics
  • Heat treating salts (steel and rubber manufacture)
  • oxidizing flux (in metallurgy)
  • Heat transfer salts, energy storage
  • Ceramics (tiles, glazes)

This product is produced under stringent specifications for applications where consistent quality is a priority. Standard grade and prilled KNO3 contain binders and other impurities.


This product can be shipped by UPS Ground to the lower 48 states only.
