What is Borides Powder?
Boride Poudre
The boron is combined with metals or non-metals. It is usually a mesenchymal material and does follow valence rules. 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 nitric hot acid. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting, abrasive and refractory materials.
Boron, a light metal, forms Borides Powder stable with transitional metals. The compounds with the highest melting points are formed from elements in groups IVA and VA or VIA. The structural characteristics of the boric atom determine the crystallographic structure of the boride. Borides Powder’s chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powder TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, structural units are formed in the form 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 boron’s atomic structure is, the less likely that it will be hydrolyzed. Its resistance to oxidation or nitridation also increases.
In transition metal Borides Powder the chemical bond is between the metal and the 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.
1.The reaction formula between metal and boron at high temperature is
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 has high conductivity as well as high melting points, hardness and stability. Boride’s thermal stability is also good because it has high thermal conductivity. The oxidation resistance at high temperatures of boride metal 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 are soluble in Nitric Acid. 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 than the metals.
Boride’s creep resistance is excellent, which makes it a great material for rockets and gas engines that need to operate at high temperatures over a long period of time. It can also resist deformation and corrosion and 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, etc.
