Boron Oxide CAS 1303-86-2

Boron oxide can be widely used as a flux in the decomposition of silicates, a dopant for semiconductor materials, an acidic catalyst in organic synthesis, a refractory additive for paints, and a raw material for the production of elemental boron and various borides. Boron (≥99.999%) is a liquid sealant in the manufacture of III~V compound semiconductors (such as gallium arsenide, gallium phosphide, and indium arsenide). In recent years, with the rapid development of the LED industry, the output of its substrate material gallium arsenide is increasing, and the demand for high-purity boron oxide is also increasing.

• Preparation of boron powder with boron oxide
  Boron oxide and aluminum powder are ground, reduced, acid-dissolved, filtered, and dried according to a certain ratio; the weight ratio of the raw material boron oxide and aluminum powder is 5:3.5-4.5; the raw material is ground to Pass through a 150-mesh sieve; the reduction temperature is 80-900°C, and the reduction time is 30-50 minutes; the acid dissolution is dissolved with hydrochloric acid with a mass concentration of 20-30%. The method of the invention is reasonable in design, strong in operability, short in preparation process, simple and controllable, light in corrosion to equipment, and high in purity and yield of the prepared boron powder.
• Preparation of green and environmentally friendly boron oxide high-grade ceramic glaze
  It is designed to solve the existing ceramic glaze materials containing lead oxide and avoid the problems of ceramic products that cause harm to the human body and the environment due to the dissolution of lead. The preparation method is as follows: the raw materials are passed through a 60-mesh standard sieve, and the part under the sieve is taken; the raw materials are mixed according to weight percentage after drying: SiO250-60%; Al2O35-8%; B2O315-2O%; Na2O2-8%; CaO2-8% ; Li2O1-2%; K2O1-2%; MgO1-2%; BaO1-2%; ZrO21-2%. The raw materials are fully stirred and mixed, then put into the furnace, melted at 1250~1300°C, and the burnt frit is poured into water to quench, and then taken out and dried to make green environmental protection boron oxide high-grade ceramic glaze. The green and environment-friendly boron oxide high-grade ceramic glaze fundamentally eliminates the threat of lead in high-grade daily-use ceramic products to human beings. At the same time, the successful use of boron oxide lead-free glaze has completely solved the problem of lead pollution in the production of high-grade ceramics from the perspective of materials and processes, which is very beneficial to protecting the health of workers and prolonging the life of kilns.
