What is Borides Powder?
Boride Poudre
The boron is combined with metals or non-metals. It can be represented as the general formula MmBn. This is a compound that does not follow valence rules and is a typical mesenchymal one. Except for zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), thallium (Tl), germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi).
Borides powder can be formed from other metals. These crystals are hard and have melting points. They are chemically inert and cannot be dissolvable by hot concentrated acid. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting, refractory and abrasive materials.
Boron, a light metal, forms Borides Powders stable with transitional metals. The compounds with the highest melting points are those formed with elements in groups IVA and VA or VIA. The structural characteristics of the boric atom determine the crystallographic structure of boride. Borides Powder’s chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powders TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, a lattice of boron is formed. This lattice contains structural units that are single bonds, dual bonds, networks, or spatial frameworks. As the proportion of boron increases in the boride, the structure unit becomes more complex.
In general, the more complex an atom’s structure is, the less likely that it will be hydrolyzed. It also has a stronger resistance to oxidation, nitridation, and other chemical reactions.
In transition metal Borides Powder the chemical bond is between the metal and boron. This electronic bond transforms the boron into a positively-charged ion.
Borides Powder: Preparation methods
Borides Powders are made by the main method of refractory metal Borides powder manufacturing.
The direct reaction between metal and boron at high temperature is 1.
Me+B—-MeB
Reducing metal oxide and boric acid with carbon is
2MeO+B2O3+5C—2MeB+5CO
Aluminum (silicon, Magnesium) Thermal method. Aluminium or silicon, magnesium reduces the oxides to generate metals and boron.
MeO+B2O3+AI – (Si,Mg )—MeB+Al oxide
Reducing metal oxides by boron carburide and carbon
4MeO+B4C+3C—4MeB+4CO
Reduce refractory metal oxides by using boron
xMeO+2xB—xMeB+(BO)x
Borides Powder: Use and nature
Boride is known for its high conductivity. It also has a high melting temperature, high hardness and high stability. The oxidation resistance at high temperatures of boride metals is based upon group IVB. Boride has the highest oxidation resistance.
Borides Powder do not react with humid air and dilute hydrochloric acids, but they do dissolve in nitric. Borides Powders are a mixture of metals and plastics. They have high conductivity as well as a positive coefficient of temperature resistance. Borides Powder of Ti Zr Hf has better conductivity compared to their metals.
Boride’s creep resistance is excellent, which makes it a great material for gas turbines or rockets. It can also resist deformation and corrosion and can withstand heat shock. Borides Powder, carbides, nitrides, or other alloys based on these materials can be used as sample holders for high temperature material testing machines and instruments, bearings, structural parts for nuclear energy devices, and components for aviation equipment.
