Black solid powder boron powder

What is boron powder?

Boron powder is a solid black powder. It has a melting point of 2360, a boiling point of about 2700, a specific gravity of 2.4, and a Mohs hardness of 9.3. It was heated in the air to 900 combustion, at 850 with molten sodium carbonate and sodium hydroxide complete reaction, borate. It does not react with water and can react with most metals to form borides at high temperatures. At a specific temperature, it is not affected by water, bromine, and chlorine. Unburned bioenergy is less soluble in water than hot nitric acid, sulfuric acid, and molten metals such as iron, magnesium, and aluminum. Low conductivity at room temperature, high conductivity at high temperature, and doping trace carbon can increase the conductivity. Explosive in contact with hydrogen iodide. Powder and air can form an ignitable mixture; when it reaches a specific concentration, it will explode when it meets Mars.

 

The use of boron powder

Boron powder can be used in superconducting materials, amorphous alloy materials, aerospace alloy materials, electronic materials, chemical anticorrosive materials, ceramics, enamel glaze, and nuclear leakage prevention materials and used as a dopant of silicon, high temperature, and high power semiconductor device material, infrared device material. Boron powder added to the metal can manufacture aircraft brake pads, welding materials, boron alloy, and amorphous materials. The unique steel made of metal with boron powder can effectively improve the wear resistance of the machine drive grinding system. The strength of glass can be increased dozens of times by adding boron powder. High-purity boron powder can also be used for processing and manufacturing drilling tools, replacing various industrial carbide drilling tools. Boron powder is widely used in military, machinery, aerospace, chemical, pharmaceutical, and other industries.

 

Physicochemical properties of boron powder

A gray-black crystal with luster. The relationship between temperature and crystal type is as follows: > 1300 is a high-temperature diamond (β-type); Tetragonal type is found at 1000 ~ 1300. The low-temperature rhomboid crystal (α-type) is located at 800 ~ 1000. The relative density is 2.34 ~ 2.37. Melting point 2300, sublimation temperature 2550. Insoluble in water, hydrochloric acid, ethanol, and ether. Soluble in cold concentrated alkali solution and decomposes hydrogen gas. It can be oxidized to boric acid by concentrated nitric acid, sulfuric acid, and aqua regia. The chemical properties are relatively active. Stable in air and at average temperature, heating to 300 is oxidized, and 700 is on fire. The flame is red when it burns and green when it is slightly vaporized boron. It can interact with oxygen, nitrogen, sulfur, halogen, and carbon at high temperatures. It can be directly combined with many metals to form metal borides. Reactions with organic compounds can produce -b-C – or -b-o-C – compounds.
