Why You Should Be Adding Borax to Your Swimming Pool

Borax.Sodium borate. Sodium tetraborate. Disodium Tetraborate. This boron compound has as many uses as it does names. While its claim to fame is as a cleaning agent (particularly as laundry detergent to brighten whites), its versatility extends to surprising uses such as the main ingredient in slime.But did you know that borax can also be a pool owner's saving grace?

Sodium Borate - an overview | ScienceDirect Topics

Sodium perborate was isolated in 1898 from the reaction of borax, sodium hydroxide, and hydrogen peroxide (3), and also electrolytically (4). In 1904, Jaubert reported the preparation of sodium perborate from boric acid and sodium peroxide, with subsequent treatment of an intermediate formulated as Na 2 B 4 O 8 ·10H 2 O with a limited amount ...

Sodium borate hydrated (Etibor 48) Anhydrous borax @ 49% B 2 O 3; Water content: @ 29%; Energy required to melt is 3,232 BTU/lb. of B 2 O 3; Boron emissions are higher up the stack requiring more frequent cleaning of precipitators and subsequent disposal costs.

Borate - Wikipedia

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 transported out using the famous twenty-mule teams from 1883 to 1889. In 1925, deposits were found at Boron, California on the edge of the Mojave Desert.

Industrial glass - Glassmaking in the laboratory | Britannica

Industrial glass - Industrial glass - Glassmaking in the laboratory: Glassmaking requires a carefully weighed selection of raw materials. For laboratory melting, a batch is prepared from reagent-grade chemicals such as floated silica, sodium carbonate, calcium carbonate, alumina, and borax—all of which are assumed to convert to equivalent amounts of oxides after decomposition.

How to Separate Precious Metal | DoItYourself.com

To create the slag, you'll need to mix in the silica and the sodium borate chemicals into the furnace and on top of the gold-plated circuit. Do this according to the usage instructions of your particular furnace and ensure that you remain safe at all times. The silica and sodium borate are collectively known as "fluxes" in this procedure.

CHEM-GUIDE: Borax, boric acid, silicate and silica

Borax can also be prepared from minerals such as boracite, colemanite, and boronatrocalcite. These minerals are powdered and boiled with sodium carbonate solution: Borax is crystallized from the filtrate. Sodium metaborate, present in the mother liquor, is converted into borax by passing carbon dioxide through it. Two important hydrates of ...

Phase separation in borosilicate and alkali earth silicate ...

Often the borate-rich phase does contain finely dispersed droplets of the silica-rich phase due to the secondary phase separation effect [1, 2, 3] during cooling of the specimen. Figure 2 displays the critical temperatures in the ternary system SiO 2 -B 2 O 3 -Na 2 O below which phase separation occurs.

Borosilicate glass - Wikipedia

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials ...
