Inventor

Sodium nitrate is the chemical compound with the formula NaNO₃. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.

Method for preparing boric acid and sodium nitrate by treating ulexite (kramerite) or ascharite with nitric acid

ActiveCN104229815AMagnesium carbonatesCalcium/strontium/barium sulfatesMagnesium carbonate hydroxideSodium nitrate

The invention discloses a method for preparing boric acid and sodium nitrate by treating ulexite (kramerite) or ascharite with nitric acid. The method is characterized by comprising the following steps: mixing ulexite (kramerite) or pulverized ascharite and a boric acid mother solution in an acidolysis reactor, heating and adding nitric acid under stirring conditions, keeping the temperature to react while timing, and finishing the reaction when the pH value of the reaction end point is stable at 2.5-4.5; and treating the mother solution four times to generate industrial boric acid, sodium nitrate, calcium sulfate and basic magnesium carbonate. The method enhances the comprehensive utilization level of the resources and increases the economic benefit.

Preparation method of refining agent for smelting fly ash doped aluminum alloy

InactiveCN103031459AReduce porosityImprove mechanical propertiesPorositySlag

The invention discloses a preparation method of a refining agent for smelting a fly ash doped aluminum alloy. The refining agent is prepared from the following raw materials in parts by weight: 6-8 parts of potassium chloride, 4-6 parts of tree ash, 6-8 parts of slag, 7-9 parts of mountain flour, 6-8 parts of zinc oxide, 3-5 parts of calcium fluoride, 3-5 parts of sodium nitrate, 5-8 parts of slag, 8-10 parts of sodium fluosilicate, 3-5 parts of sodium sulfate, 5-8 parts of aluminum chloride, 3-5 parts of potassium carbonate, 8-10 parts of sepiolite, 5-8 parts of NaBF4, 3-5 parts of sodium chloride, 5-8 parts of calcium carbonate, 8-10 parts of Na2TiF68 and 5-8 parts of NaF. The refining agent disclosed by the invention is used for treating to obtain a high-quality molten aluminum alloy; the molten aluminum alloy can be used for casting production and the rate of finished products is obviously improved; particularly, the porosity in a cast is reduced by 1-2 degrees and is effectively controlled; pores are not formed on the surface of the cast, oxide inclusion is obviously reduced and the oxide inclusion is about grade 2; and the mechanical property of the cast is obviously improved.
