Borax, также известная как Борат натрия, тетраборат натрия, или двунатриевый тетраборат, является важным соединением бора, минерала, и соль борной кислоты. Обычно это белый порошок, состоящий из мягких бесцветных кристаллов, которые легко растворяются в воде\.nBorax н\имеет широкий спектр применения. Он является компонентом многих моющих средств, косметики, эмали и глазури. Он также используется для приготовления буферных растворов в биохимии, в качестве огнеупорной добавки, как противогрибковый препарат для стеклоткани, в качестве флюса в металлургии, нейтронно-захватная щиты для радиоактивных источников, а текстурирование агент в кулинарии, и как прекурсор для других соединений бора.\н\пкоманды термин бура применяют для ряда родственных минералов или химических соединений, которые отличаются своим кристально содержание воды, но, как правило, относится к декагидрат. В продаже продается бура, как правило, частично обезвоживается.

Use
Household products Borax is used in various household laundry and cleaning products, including the " 20 Mule Team Borax " laundry booster and " Boraxo " powdered hand soap.
Buffer Sodium borate is used in biochemical and chemical laboratories to make buffers, e. g. for gel electrophoresis of DNA, such as TBE or the newer SB buffer or BBS ( borate buffered saline ) in coating procedures.
Co-complexing Borax as a source of borate has been used to take advantage of the co-complexing ability of borate with other agents in water to form complex ions with various substances. Borate and a suitable polymer bed are used to chromatograph non- glycosylated hemoglobin differentially from glycosylated hemoglobin (chiefly HbA1c ), which is an indicator of long term hyperglycemia in diabetes mellitus. Borate and a proprietary synthetic amino acid, Deselex (from Henkel ) have been used to complex water " hardness" cations to make a non- precipitating water " softener" .
Flux A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also used mixed with water as a flux when soldering jewelry metals such as gold or silver. It allows the molten solder to flow evenly over the joint in question. Borax is also a good flux for ' pre-tinning' tungsten with zinc - making the tungsten soft-solderable.
Small-scale mining Borax is replacing mercury as the preferred method for extracting gold in small-scale mining facilities. The method is called the borax method and is used in the Philippines.
Putty A rubbery polymer sometimes called flubber, gluep or glurch can be made by cross linking polyvinyl acetate with a borax. Making flubber from polyvinyl acetate based glues, such as Elmer' s Glue, and borax is a common elementary education experiment.
Food additive Borax, given the E number E285, is used as a food additive in some countries, but is banned in the US. As a consequence, certain foods, such as caviar, produced for sale in the US contain higher levels of salt to assist preservation. Its use as a cooking ingredient is to add a firm rubbery texture to the food, or as a preservative. In oriental cooking it is mostly used for its texturing properties. In Asia, Borax  was found to have been added to some Chinese foods like hand-pulled noodles lamian and some rice noodles like Shahe fen, Kway Teow, and Chee Cheong Fun recipes. In Indonesia it is a common, but forbidden, additive to such foods as noodles, bakso (meatballs), and steamed rice.
Other uses
1)Ingredient in enamel glazes
2)Component of glass, pottery, and ceramics
3)Borax can be used as an additive in ceramic slips and glazes to improve
fit on wet, greenware, and bisque.

13) Fluoride detoxification
14)Treatment for thrush in horses ' hooves
15)Used to make indelible ink for dip pens by dissolving shellac into heated borax
16)Curing agent for snake skins
17)Curing agent for salmon eggs, for use in sport fishing for salmon
18)Swimming pool buffering agent to control the pH
20)As a micronutrient fertilizer to correct boron-deficient soils.
21)To clean the brain cavity of a skull for mounting
22)To color fires with a green tint
23)Was traditionally used to coat dry-cured meats such as hams to protect them from becoming fly-blown during further storage.
24)Is found in some commercial vitamin supplements
25)For stopping car radiator and engine block leaks
26)As an important component in Slime
