Sodium Tetraborate Decahydrate is also called Borax.
Sodium Tetraborate Decahydrate is a salt (ionic compound), a hydrated borate of sodium, with chemical formula Na2H20B4O17 often written Na2B4O7·10H2O.

Sodium Tetraborate Decahydrate is a colorless crystalline solid, that dissolves in water to make a basic solution.
Sodium Tetraborate Decahydrate is commonly available in powder or granular form, and has many industrial and household uses, including as:

-pesticide

-metal soldering flux

-component of glass

-enamel, and pottery glazes

-for tanning of skins and hides

-for artificial aging of wood

-preservative against wood fungus

-pharmaceutic alkalizer

In chemical laboratories, Sodium Tetraborate Decahydrate is used as a buffering agent.
Sodium Tetraborate Decahydrate is often called sodium tetraborate decahydrate, but that name is not consistent with its structure.

The anion is not tetraborate [B4O7]2− but tetrahydroxy tetraborate [B4O5(OH)4]2−, so the more correct formula should be Na2B4O5(OH)4·8H2O.
Informally, the product is often called sodium borate decahydrate or just sodium borate

The crystalline decahydrate is a proton conductor at temperatures above 21 °C.
Conductivity is maximum along the b axis.

Sodium Tetraborate Decahydrate's Reactions:
Sodium Tetraborate Decahydrate is also easily converted to boric acid and other borates, which have many applications.
Sodium Tetraborate Decahydrate's reaction with hydrochloric acid to form boric acid is:

Na2B4O7·10H2O + 2 HCl → 4 H3BO3 + 2 NaCl + 5H2O

The "decahydrate" is sufficiently stable to find use as a primary standard for acid base titrimetry.
Molten borax dissolves many metal oxides to form glasses.
This property is important for its uses in metallurgy and for the borax bead test of qualitative chemical analysis.

Sodium Tetraborate Decahydrate's Natural Sources:
Sodium Tetraborate Decahydrate occurs naturally in evaporite deposits produced by the repeated evaporation of seasonal lakes.
The most commercially important deposits are found in: Turkey; Boron, California; and Searles Lake, California.
Also, Sodium Tetraborate Decahydrate has been found at many other locations in the Southwestern United States, the Atacama desert in Chile, newly discovered deposits in Bolivia, and in Tibet and Romania.
Sodium Tetraborate Decahydrate can also be produced synthetically from other boron compounds.
Naturally occurring Sodium Tetraborate Decahydrate (known by the trade name Rasorite–46 in the United States and many other countries) is refined by a process of recrystallization.

USES:
Ant control:
Sodium Tetraborate Decahydrate is used in control solutions because it is toxic to ants.
Because it is slow-acting, worker ants will carry the borax to their nests and poison the rest of the colony.

Household products:
Sodium Tetraborate Decahydrate is used in various household laundry and cleaning products, including the 20 Mule Team Borax laundry booster, Boraxo powdered hand soap, and some tooth bleaching formulas.

pH buffer:
Borate ions (commonly supplied as boric acid) are used in biochemical and chemical laboratories to make buffers, e.g. for polyacrylamide gel electrophoresis of DNA and RNA, such as TBE buffer (borate buffered tris-hydroxymethylaminomethonium) or the newer SB buffer or BBS buffer (borate buffered saline) in coating procedures.
Borate buffers (usually at pH 8) are also used as preferential equilibration solution in dimethyl pimelimidate (DMP) based crosslinking reactions.

Co-complexing agent:
Sodium Tetraborate Decahydrate 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-glycated hemoglobin differentially from glycated hemoglobin (chiefly HbA1c), which is an indicator of long-term hyperglycemia in diabetes mellitus.

Flux:
A mixture of Sodium Tetraborate Decahydrateand ammonium chloride is used as a flux when welding iron and steel.
Sodium Tetraborate Decahydrate lowers the melting point of the unwanted iron oxide (scale), allowing it to run off.
Sodium Tetraborate Decahydrate is also used mixed with water as a flux when soldering jewelry metals such as gold or silver, where it allows the molten solder to wet the metal and flow evenly into the joint.
Sodium Tetraborate Decahydrate is also a good flux for "pre-tinning" tungsten with zinc — making the tungsten soft-solderable.
Sodium Tetraborate Decahydrate is often used as a flux for forge welding

Flubber:
A rubbery polymer sometimes called Slime, Flubber, 'gluep' or 'glurch' (or erroneously called Silly Putty, which is based on silicone polymers), can be made by cross-linking polyvinyl alcohol with borax.
Making flubber from polyvinyl acetate-based glues, such as Elmer's Glue, and borax is a common elementary-science demonstration.
