Nature of Boron Powder Brown powder. The relative density is 1.73, the melting point is 2190°C, and the boiling point is 3660°C. Unaffected by water, bromine and chlorine at certain temperatures. Unburned Boron can be absorbed in hot nitric acid, sulfuric acid and molten metals, such as iron, magnesium, aluminium, etc., and is insoluble in water. The electrical conductivity is low at room temperature, and the electrical conductivity is high at high temperature, and the electrical conductivity can be increased after doping with trace carbon. Contact with hydrogen iodide can explode. Powder and air can form an explosive mixture, and when it reaches a certain concentration, it will explode when it encounters Mars. It is a solid black powder. Its melting point is 2360°C, boiling point is about 2700°C, specific gravity is 2.4, and Mohs hardness is 9.3. It is heated to 900°C in air, burns, and completely reacts with molten sodium carbonate and sodium hydroxide at 850°C to form borate. It does not react with water. It can react with most metals at high temperatures to form corresponding borides.
What is Boron Powder used for? 1. Boron powder can be used to make various compounds containing Boron as a raw material for the production of boron fibres and as an important raw material for the manufacture of high-purity boron halides. 2. Boron is added as compounds Used in the smelting of special alloy steels or as a gas scavenger for molten steel. 3. High energy fuel for spacecraft used in rockets. 4. as ignition poles for ignition tubes in the electronics industry. 5. In lieu of precious or scarce metals. 6. Protective material for the atomic industry, control rods in atomic reactors.
The manufacturing method of Boron Powder 1. Weighing the reaction materials; the reaction materials include 40-48% by mass of Mg powder, 35-42% by mass of B2O3 powder and 10-24% by mass of diluent powder, where the diluent powder is any one of KCl, MgCl2 and NaCl. 2. Mixing of the reaction raw materials and pressurisation of the mixed reaction raw materials to obtain round cake blanks. 3. First, put the billet into the combustion synthesis reactor and place the igniter on the upper surface of the billet; secondly, fill the reactor with 0.5MPa argon gas, wait until the temperature inside the reactor is heated to 110℃~130℃, discharge the gas inside the reactor until the pressure is 0 and then stop the gas discharge, wait until the temperature inside the reactor is heated to 170℃~190℃ again, discharge the gas inside the reactor completely and keep it warm 0.5h. Then again, fill the reaction kettle with argon gas to make the pressure in the reaction kettle rise to 1Mpa~3Mpa; when the temperature in the reaction kettle rises to 250℃~270℃, the magnesium heat reaction occurs in the reaction kettle; finally, when the magnesium heat reaction is completed and cooled to room temperature, the lump containing boron powder is obtained. 4. The impurity removal of the lump containing boron powder was obtained using an acid-water washing immersion process to obtain ultra-fine amorphous boron powder with high purity and small particle size.
Price of Boron Particle size and purity will affect the product's price, and the purchase volume can also affect the cost of particle size. A large amount of large amount will be lower. The price of particle size can be found on our company's official website.
