Zirconium Diboride ZrB2 Pulver:
Zirconium bore chemical substance. Zirconium boreide chemical formula, is ZrB2. Nature gray hard crystals. The three main components of zirconium bore are zirconium monoboride zirconium disboride, zirconium tribromide. The stability of zirconium boride in wide temperatures is limited to the diboride. The main component of industrial production is zirconium boride. Zirconium dioxide is either a hexagonal or gray crystal or powder. It has an relative density 5.8 and a 3040°C melting point. This product can withstand high temperatures, and it also has high resistance at high and room temperature. High resistance to thermal shock, high resistance to oxidation and good resistance at low temperatures. Metallic luster. The melting point is approximately 3000°C.
Zirconium boride ZrB2 a high-covalent, refractory ceramic with a hexagonal crystal construction. ZrB2 can be described as an ultra-hightemperature ceramic (UHTC), with a melting temperature of 3246°C.
The unusual ceramic is extremely thermally and electrically conductive and shares many of the characteristics with titanium diboride. ZrB2 is able to pass EDM basic clay molding due to its excellent electrical conductivity and fire resistance.
ZrB2 parts can be hot-pressed, which means that they are heated and pressurized to melt the powder. ZrB2 is not able to be sintered due to the covalent nature of its material and the existence of surface oxides. Surface oxides may cause the crystal grains to become coarser before they are able to withstand densification. ZrB2 can also be sintered under pressure. The surface oxides will react with the sintering additives carbon and boron, increasing the driving force of sintering. But, mechanical properties will decline compared to ZrB2 hot-pressed.

Zirconium Diboride (ZrB2), a high-covalent refractory ceramic materials with hexagonal crystal structures, is extremely covalent. ZrB2 has an ultra high-temperature ceramic (UHTC), with a melting points of 3246°C. (measured densities may be greater due to hafnium impureties). It is a good candidate for aerospace applications, such as rocket propulsion or hypersonic flight. The unusual properties of this ceramic are shared with the hafnium diboride (structural titanium diboride) and it has high thermal and electric conductivities.
How Zirconium Diboride ZirB2 powder is produced?
By metal thermal reduction, ZrO2 or HfO2 can be reduced to the respective diboron silanes. You can use cheap precursor material and follow the reactions below:
ZrO 2 + B 2 O 3 + 5Mg→ZrB 2 + 5MgO
Precursor materials (ZrO 2, TiO 2, / HfO2 and B4 C) for this reaction are less expensive than those needed for stoichiometric, boron thermoreactions. The following reactions will allow you to prepare ZrB2 at temperatures higher than 1600°C.
2ZrO 2 + B 4 C + 3C→2ZrB 2 + 4CO
Due to the fact that some of the boron will be oxidized by the boron carbide removal process, there is an excess of boron. ZrC is the end product of this reaction. But, when the excess of 20-25% B4C is exceeded, ZrC disappears leaving only ZrB2. UHTC produced at a lower synthesis temperature (1600°C), will yield finer particles and better interability. The boron-carbidide must be ground before it can undergo oxide reduction or diffusion.
You can disperse ZrO2 as well as HfO2 on the boron carbonide polymer precursor prior to the reaction. in. By heating the mixture at 1500°C, boron carbide is formed and carbon in situ. ZrO2 and ZrB2 are then reduced.
If the substrate is above 800°C, then the vapors from zirconium titanate and boron trichloride are reduced by the use of the gas phase.
Zirconium Diboride ZrB2 powder –
Zirconium dioxide has high hardness and thermal conductivity. They are also resistant to corrosion. Zirconium diboride can be found in special ceramic and refractory industry, military industry, the nuclear industry, aerospace, and military industry. Zirconium boride can also be used to coat surfaces of rolling balls or smooth solid materials.
High density carbon fiber reinforced zirconium-diboride composites have exceptional strength, while those made with silicon carbide fibre-reinforced diboride compounds are fragile and can cause catastrophic injury.
Zirconium biboride (ZrB2) has the ability to be used for thin-film electronic components in sensor, actuators and microsystems that operate at high temperature environments. This is because of its metal-like conductivity. Also, it has a melting temp.
Zirconium Diboride ZrB2 Pulse can be used for other purposes:
(1) Zirconium Diboride Powder is used in the manufacture of ceramics.
