Such layers outperform traditional soft solder layers in thermal resistance and reliability thanks to their high melting point, high thermal conductivity and typically thin bond line. But the process is still pretty new and requires new equipment to apply the required amount of pressure.
As a ceramic material, tungsten carbide has to be compacted at high temperatures of between 1 900 and 2 200 °C. That is why we use hot pressing techniques to produce our targets and achieve at least 99 % of the theoretical density. As a result, no particles of powder are released from the target during sputtering and the coating adheres perfectly.
Extrusion dies are exposed to high mechanical pressures.A high level of frictional heat is also generated between the die and the workpiece. Clearly a job for us. By adding small quantities of hafnium carbide, we get our molybdenum ready for a long service life in your extrusion press.

The reason why is has such a high melting point is to do with its structure- Silicon Dioxide has a giant covalent structure (much like diamond and graphite- allotrope''s of carbon). .
Quartz, on the hardness scale is 7, which is nice and hard, that is compared to most things you might be sanding. So the quartz can easily scratch them, which of course is the posses of sanding.
Silicon is the most abundant element on earth after oxygen.Large amounts of silicon can be found in various minerals and it is abundant in oceans and nearly all other waters as silicic acid. In the surface layers of oceans silicon concentrations are 30 ppb, whereas deeper water layers may contain 2 ppm silicon.
