Product Description

Zirconium Diboride is a kind of ceramic material  Melting point: 3246 centi-grade


Zirconium diboride (ZrB2) industrial grade : 90%, 98% min. is a kind of ceramic material with a hexagonal crystal structure  ZrB2 is an Ultra High Temperature Ceramic (UHTC) with a melting point of 3246 °C  This along with its relatively low density of ~6.09 g/cm3 (measured density may be higher due to impurities) and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems


ZrB2 parts are usually hot pressed (pressure applied to the heated powder) and then machined to shape  Sintering of ZrB2 is hindered by the material's covalent nature and presence of surface oxides which increase grain coarsening before densification during sintering  Pressureless sintering of ZrB2 is possible with sintering additives such as Boron Carbide and Carbon which react with the surface oxides to increase the driving force for sintering but mechanical properties are degraded compared to hot pressed ZrB2


Additions of ~30 vol% SiC to ZrB2 is often added to ZrB2 to improve oxidation resistance through SiC creating a protective oxide layer - similar to aluminum's protective alumina layer
