Non-oxide Ceramics

Tungsten Carbide

Tungsten Carbide, WC, is often found in cutting tools used for machining of metals. It is stiffer, harder and much denser than hardened steel.

Besides cutting tools, the material is employed in many different shapes and sizes as wear components and tools within the mining and construction industry.

Boron Carbide

Boron carbide, B4C, is a ceramic material known to be one of the world's hardest materials, ranking third behind diamond and cubic boron nitride. Furthermore, the material shows advantages such as very low density, high Young’s modulus, and chemical inertness to corrosive media.

These properties have been proven useful in a variety of applications like ballistic protection and wear-resistant components. Boron carbide is also employed in the nuclear energy industry, due to its excellent neutron absorption ability.

Silicon Carbide

Silicon carbide, SiC, is very hard and light.  The ceramic maintains its properties at a wide spectrum of temperatures, making it suitable for high temperature applications such as abrasives, high performance car brakes and clutches. Due to its hardness, silicon carbide can also be used in ballistic protection.

Silicon Nitride

Silicon nitride, Si3N4, is ideal for components working under mechanical loads at elevated temperatures. It has extremely high strength, wear resistance and an excellent resistance to sudden temperature changes. It is commonly used in gas turbines, engines and cutting tools.

Diamorph has expertise in sintering silicon nitride as well as sialon, a solid solution of silicon nitride enriched with aluminium and oxygen. The family of silicon nitride and sialon is currently the best choice for ceramic bearing elements.

Uranium Nitride

Uranium Nitride is currently being explored as a potential fuel for generation IV nuclear reactors due to it's high number density and excellent thermal conductivity.

Diamorph is in collaboration with the Royal Institute of Technology of Stockholm in nuclear fuel research where our expertise in sintering is used to produce uranium nitride pellets.

Titanium Diboride

Titanium diboride, TiB2, has high hardness, good thermal shock resistance, a high melting point, chemical inertness and durability, good thermal and electrical conductivity.

It has various structural applications, specifically in the armor and wear resistant industries due to its exceptionally hard nature.

At Diamorph, one of the applications of TiB2 is in the use of functionally graded material where it gradually shifts from titanium diboride to a combination of titanium and titanium diboride, combining the ceramic’s ability to absorb energy with the toughness of a metal - ideal for vehicle armor solutions.
