Zirconium boride is a highly covalent refractory ceramic material with hexagonal crystal structure. ZrB2 is an ultra-high temperature ceramic with a melting point of 3246℃. The relatively low density (about 6.09 g/cm³) and good high-temperature strength make it a candidate material for high-temperature aerospace applications such as hypersonic flight or rocket propulsion systems.
Zirconium boride is one of the main and common materials in boride. There are three types of zirconium boride in the boron-zirconium system: zirconium monoboride, zirconium diboride, and zirconium dodecylboride, among which zirconium diboride is stable in a wide temperature range, and industrial production The prepared zirconium boride and its applications are mostly based on zirconium diboride. Zirconium boride is a cubic C32 type metalloid structure compound. The Zr-B ionic bond between the boron atom face and the zirconium atom face and the strong bond of the BB covalent bond determine the high melting point and high hardness of this material. And stability. Therefore, zirconium boride has the characteristics of high melting point, high hardness, high stability, good electrical conductivity, thermal conductivity and good corrosion resistance.
There are many methods for preparing zirconium boride, which come down to the following: solid phase method, carbothermal method, metal thermal reduction method, self-propagating high temperature synthesis method and electrochemical synthesis method, gas phase method, mechanochemical method, etc.
Because of its excellent characteristics, zirconium boride has been widely used as various high-temperature materials and functional materials, such as continuous temperature measuring sleeve for molten steel, continuous cast steel immersion nozzle, turbine blades for aerospace industry, magnetic fluid generator electrodes and special circuits High temperature heating materials, cutting tools, etc.
With the development of modern technologies such as aerospace, aviation, atomic energy, smelting technology, etc., more and more stringent requirements are placed on high-temperature structural materials, which require materials to have good high-temperature performance to adapt to harsh operating environments, such as thermal shock resistance, high temperature strength , Corrosion resistance, oxidation resistance, etc. Because of its advantages of high melting point, high hardness, good electrical and thermal conductivity, and good neutron control capabilities, zirconium boride ceramics have been popular in the fields of high-temperature structural ceramic materials, composite materials, refractory materials, electrode materials, and nuclear control materials.
