Hojo et al. reported on the production of nanosized tungsten carbide powder by vapor phase reaction of WCl 6 -CH 4 -H 2 system in a horizontal tube reactor. The particle size of WC was affected by reaction temperature, with about 40-50 nm for a low temperature of 400 °C and about 80-110 nm for a high temperature above 1000 °C.

In order to obtain a dense tungsten body, a conventional MIM process for net-shaped tungsten-based composites demands a multi-component binder system for liquid binder mixing and sintering temperatures over 2000 °C,,,,,, . A multi-component binder system is commonly used to maintain the shape of a molded part while each binder component
Laser Chemical vapor deposition (LCVD) - This CVD process uses lasers to heat spots or lines on a substrate in semiconductor applications. In MEMS and in fiber production the lasers are used rapidly to break down the precursor gas-process temperature can exceed 2000 °C-to build up a solid structure in much the same way as laser sintering based
The cold compacted pellets were sintered in a vacuum tube furnace. Cold compaction pressure, sintering temperature and holding time were optimized for maximum densification and the composites were produced with different volume percent of diamond particles at optimized parameters.
