Tincalconite is a hydrous sodium borate mineral closely related to borax, and is a secondary mineral that forms as a dehydration product of borax. Its formula is Na 2 B 4 O 7 ·5H 2 O or Na 2 [B 4 O 5 (OH) 4]·3H 2 O. Tincalconite typically occurs as a fine grained white powder.
Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid, although the latter may not be a stable compound.
Borax is also easily converted to boric acid and other borates, which have many applications. Its reaction with hydrochloric acid to form boric acid is: Na 2 B 4 O 7 ·10H 2 O + 2 HCl → 4 H 3 BO 3 + 2 NaCl + 5 H 2 O. Borax is sufficiently stable to find use as a primary standard for acid-base titrimetry. [17]: p.316
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
Borax crystals. Common borate salts include sodium metaborate (NaBO 2) and borax. Borax is soluble in water, so mineral deposits only occur in places with very low rainfall. Extensive deposits were found in Death Valley and shipped with twenty-mule teams from 1883 to 1889. In 1925, deposits were found at Boron, California on the edge of the ...
Borateem, now manufactured by Dial Corporation, is a chlorine-free, color safe bleach powder but it has no borax content. Boraxo , also originally a 20 Mule Team product, was a borax-based powdered hand soap manufactured in the past by Pacific Coast Borax Company, then by US Borax via merger, and finally acquired by Dial.

The solution of orthoboric acid and borax in 4:5 ratio is used as a fire retarding agent of wood by impregnation. [38] It is also used in the manufacturing of ramming mass, a fine silica-containing powder used for producing induction furnace linings and ceramics. Boric acid is added to borax for use as welding flux by blacksmiths. [39]
Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, [5] is an inorganic compound with the formula Na B H 4 (sometimes written as Na[BH 4]).It is a white crystalline solid, usually encountered as an aqueous basic solution.
