sodium tetraborate การใช้

• Barium borate monohydrate is prepared from the solution of barium sulfide and sodium tetraborate.
• You could also get borax ( sodium tetraborate decahydrate ) at the grocery store.
• Borates, such as borax ( sodium tetraborate ), boric acid and sodium metaborate, are toxic to plants, even at a concentration of 100 ppm.
• This has led to imports of sodium tetraborate ( borax ) growing by a hundredfold between 2000 and 2005 and boric acid imports increasing by 28 % per year over the same period.
• Boric acid, mixed with borax ( sodium tetraborate decahydrate ) at the weight ratio of 4 : 5, is highly soluble in water, though they are not so soluble separately.
• Boron supplements derive from dry lake bed deposits such as those in Death Valley, USA, in the form of sodium tetraborate ( borax ), from which less soluble calcium borate is made.
