Technical sodium nitrate is produced in two grades depending on application: A grade is used in preparation of fluxes for metal welding/soldering; in production of reagents, pyrotechnic mixtures, optical glass, crystal glass and in production processes in which content of oxidizable substances as NaNo2 is strictly limited. B grade is used in metal etching, melting lump waste tungsten, technical glass fining and in retail sale.

Attention! Sodium nitrate is toxic. When getting into human body it may cause formation of methemoglobin in blood. It is not combustible. Being an oxidizer, it promotes self-ignition of combustibles. In case of fire use OXP-10 or OBP-10 fire extinguishers and abundant amount of water. Packing: in 5-, 6-layer bituminized or 5-layer paper laminated bags, 5-layer paper unimpregnated bags with PE liners. Transportation: by all means of conveyance except by air transport, in covered conveyances in accordance with existing rules for hazardous cargo carriage. Storage life: unlimited.
