Flux boron powder

What is boron powder?

Boron powder is a brown powder. Relative density 1. 73; The melting point is 2190 , and the boiling point is 3660 . It is not affected by water, bromine, and chlorine at a certain temperature. "Unburned boron is soluble in hot nitric acid, sulfuric acid, and molten metals such as iron, magnesium, and aluminum, and is insoluble in water.". The conductivity is low at room temperature and high at high temperatures. Doping trace carbon can increase conductivity. Contact with hydrogen iodide can explode. Powder and air can form explosive mixtures, and when they reach a certain concentration, they will explode when they encounter Mars.


Uses of boron powder

Boron powder can be used in superconducting materials, amorphous alloy materials, aerospace alloy materials, electronic materials, chemical anti-corrosion materials, ceramics, enamel glaze, and nuclear leakage prevention materials. Used as a dopant for semiconductor material silicon, high-temperature, high-power semiconductor device material, and infrared device material. Boron powder can be added to metal to make aircraft brake pads, welding materials, boronated alloys, and amorphous materials. Special steel made of metal added with boron powder can effectively improve the wear resistance of transmission and grinding systems in the mechanical industry. Adding a certain amount of boron powder into glass processing can improve the strength of glass by tens of times. High-purity boron powder can also process and manufacture drilling tools, replacing various industrial cemented carbide drilling tools. Boron powder is widely used in military, mechanical, aerospace, chemical, pharmaceutical, and other industries.

 

Preparation of boron powder

First, use concentrated alkali solution to decompose the boron magnesium ore to obtain sodium metaborate, crystallize NaBO ₂ in a strong alkali solution, dissolve it in water to form a relatively concentrated solution, add CO ₂ to adjust the alkalinity, and concentrate and crystallize to obtain sodium tetraborate (borax). Boric acid crystals with low solubility can be precipitated by dissolving borax in water and adjusting the acidity with sulfuric acid. Heating dehydrates boric acid to produce boron trioxide, and after drying, B ⏴ O ⏴ is reduced with magnesium or aluminum to obtain crude boron. Brown amorphous boron with a purity of 95 to 98% can be obtained by treating the crude boron with hydrochloric acid, sodium hydroxide, and hydrogen fluoride, respectively.

 

Price of boron powder

Boron powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of boron powder. A large amount of large amount will be lower. The Price of boron powder is on our company's official website.
