  • Physical properties Colorless glassy solid or vitreous crystal; hexagonal crystal system; slightly bitter taste; hygroscopic; density 2.55 g/cm3; melts at 450°C; vaporizes at 1,500°C; slightly soluble in cold water (3.3%), soluble in alcohol and boiling water (20%).
  • Uses A saturated solution of H3BO3 contains about 2% of the compound at 0 C, increasing to about 39% at 100 C. The compound also is soluble in alcohol. In preparations, solutions of boric acid are nonirritating and slightly astringent with antiseptic properties. Although no longer used as a preservative for meats, boric acid finds extensive use in mouthwashes, nasal sprays, and eye-hygiene formulations. Boric acid (sometimes with borax) is used as a fire-retardant. A commercial preparation of this type (Minalith) consists of diammonium phosphate, ammonium sulfate, sodium tetraborate, and boric acid. The tanning industry uses boric acid in the deliming of skins where calcium borates, soluble in H2O, are formed. As sold commercially, boric acid is B3O3·3H2O, prepared by adding HCl or H2SO4 to a solution of borax. In preparation of fluxes; component of enamels and glass; catalyst in organic reaction Boron oxide was used as the intermediate glass layer at a bonding temperature of 450°C. In preparation of fluxes; component of enamels and glass; catalyst in organic reaction. In metallurgy; in analysis of silicates to determine SiO2 and alkalies; in blowpipe analysis.

Production of aluminum-titanium-boron master alloy by aluminothermic process

10.1515/HTMP.2001.20.2.137

Onuralp Yücel and Filiz ?inar Sahin investigate the production of Al-Ti-B master alloys using an aluminothermic reduction process. The study aims to determine optimal parameters for producing these alloys from titanium oxide (TiO2) and boron oxide (B2O3). The authors found that adding a thermite mixture of potassium chlorate and aluminum significantly affected the titanium (Ti), boron (B), and aluminum (Al) content of the alloy, as well as their recoveries. At a B2O3/TiO2 ratio of 0.22 and with a 50% thermite mixture by weight, they produced an alloy containing 49.8% Ti, 5.7% B, and 24.7% metallic Al, with 46.9% Ti and 47.7% B recoveries. Increasing the B2O3/TiO2 ratio to 0.33 and maintaining a 50% thermite mixture resulted in an alloy with 51.2% Ti, 7.9% B, and 28.1% Al, with 55.6% Ti and 50.7% B recoveries. The study also explored the effects of adding CaO as a flux, which did not improve metal recoveries but significantly decreased them at higher ratios due to its high heat sink effect. The results indicate that the aluminothermic process can effectively produce Al-Ti-B alloys with suitable compositions and high recoveries of Ti and B, making it a viable method for industrial applications.
