Pure tungsten carbide (WC) compacts of about 200 nm grain size were prepared by high
pressure and high temperature (HPHT) method. The best property sample with high relative …

Extremely dense WC with a relative density of up to 99% was obtained within 3min under a
pressure of 80MPa using the high frequency induction heating sintering method (HFIHS) …

The chemical activation pretreatment was executed on the WC powder and the WC-Y 2 O 3
composite powder was prepared by the chemical liquid mixing method. The binderless …

Binderless tungsten carbide with varied amounts of ZrC nano-powder (0–9 wt.%) were
prepared by spark plasma sintering at 1600° C under an applied pressure of 50 MPa. The …

In this study, binderless WC ceramics with grain size of 210 nm were obtained under a high-
pressure of 200 MPa at a relatively low temperature of 1550° C. The effects of high pressure …

Nano sized tungsten carbide (n-WC) compacts with and without grain growth inhibitors were
synthesized by Spark Plasma Sintering (SPS) with different heating rates. The microstructure …

Tungsten carbide (WC), consolidated by liquid phase sintering with the metallic binder Co, is
used for enhanced performance cutting tools, dies, and wear-resistant parts requiring high …

The aim of this study was to produce dense, single phase polycrystals. The research was
carried out on the submicron tungsten carbide powder without additives, with either a carbon …

In this work, we present a novel method to sinter tungsten bulk material under high pressure
without any additives. The sintering temperatures were greatly reduced in our experiments …

WC-cBN composites without any additives were synthesized by High Pressure-High
Temperature (HPHT) method. The effect of sintering temperature, cBN content, and particle …
