Abstract: An improved method is provided for producing crystalline calcium hexaborate tetrahydrate, synthetic nobleite, by the reaction of boric acid and lime in an aqueous slurry. Reaction conditions include boric acid to water molar ratios of greater than 0.25:1, lime to boric acid molar ratios in the range of 0.05-0.15:1 and temperatures in the range of 85 °C - 105 °C. A novel crystalline product is produced having a unique crystal habit resulting in improved physical properties. Dehydration of this product produced a novel amorphous, anhydrous product having similar crystal habit and physical properties.

Abstract: The present invention relates to boron-containing compositions. The invention relates to comminuted, heterogeneous boron-containing compositions which are obtainable by a process which comprises heating to a temperature sufficiently high that calcination occurs but insufficient for the formation of a homogeneous melt a mixture comprising components capable, under the conditions of heating, of forming the oxides B2O3 and SiO2 and optionally Al2O3, Na2O and/or CaO in proportions such that the relative percentages by weight of the said oxides, based on the total weight of said oxides, are as follows: 5 to 35% B2O3; 10 to 65% SiO2; 0 to 35% Al2O3; and up to 20% Na2O and/or up to 50% CaO; with the proviso that the said B2O3 content is not 10 to 18%, when the other contents are as follows: 40 to 65% SiO2, 17 to 32% Al2O3 4 to 9% Na2O, and O to 10% CaO, and then comminuting the resulting composition. By varying the proportions of the ingredients and the heating conditions, there may be obtained products of differing boron solubility characteristics according to the desired use of the products. Such compositions may be used as a source of boron in ceramics and heavy clay bodies, glass and fiberglass; in agriculture; as wood preservatives and pesticides; in polymers and rubbers; in wood, including wood-plastic composites; as flame retardant; in intumescent materials; in paints and coatings, in soaps and detergents; in cosmetics; in industrial fluids; in steel slag; in water treatment; and in gypsum wallboard as well as in glazes.

Abstract: The addition of zinc borate alone or together with a hindered amine light stabilizer and ultra-violet light absorber to organic materials such as thermoplastic polyolefin resin, as is common in wood-plastic composites, provides a substantial reduction in the ultra-violet light degradation of the resin in comparison with similar materials made without zinc borate. This could provide substantial improvements in the long term durability of wood-plastic composites and other organic materials which are used in exterior environments and subject to ultra-violet exposure from the sun.

Abstract: Lignocellulosic-based composite products containing a pesticidal amount of calcium borate is resistant to attack by wood destroying fungi and insects. The preferred calcium borates are the calcium polytriborates having a CaO:B2O3 molar ratio of about 2:3 and calcium hexaborates, having a CaO:B2O3 ratio of 1:3. Composites can be produced by combining the calcium borate with particles of the lignocellulosic material and an adhesive resin, and forming the composite, generally with heat and pressure.
