REACTIONS TAKING PLACE DURING SMELTING

By this method, it was found that up to 500°F. the chief reaction was the dehydration of the borax. Between 500° and 800°F., the first liquid developed with the melting of the soda niter. Most of the reactions, however, took place from 800° to 1300°F. Soda niter and sodium silicofluoride were decomposed, and the antimony trioxide was oxidized.

Borax: helps collect iron and a good fluidizing agent. Boric acid: helps collect iron but gives a thicker smelt than borax. Silica Flour: provides silicon for slag and helps collect iron. Sodium Nitrate: Strong oxidising agent – oxidises iron but very damaging on crucibles if used too generously. Soda Ash: Fluidizes slag but works against nitre.

Borax - Wikipedia

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is a compound with formula Na 2 H 4 B 4 O 9 •nH 2 O or, more precisely, [Na•(H 2 O) + m] 2 [B 4 O 5 (OH) 2− 4]. The formula is often improperly written as Na 2 B 4 O 7 •(n+2)H 2 O, reflecting an older incorrect understanding of the anion's molecular structure.
