Sintering behavior of spherical mono

Inert gas atomized mono-sized tungsten powders were cold pressed at 130 MPa and then sintered in the temperature range (0 52–0 73) T m for different times under hydrogen atmosphere The sintering kinetic was monitored by measuring shrinkage and density evolution and compared with commercially reduced tungsten powder

In our past article we provided an overview of the material known as Tungsten Carbide In this follow up we'll tell you how this key material is made Tungsten has the highest melting point of all metals at 3410 o C (6170 o F) In order to create parts made from tungsten or tungsten alloys like tungsten carbide the typical process of melting and blending of the metal and alloying elements

Spherical tungsten can also be made by the use of a plasma torch ^^^'^* Tungsten powder can be spheroidized in principle at least by dropping it through a resistance-heated graphite tube ^^^ One producer has made spheres in the range 75 to 150 microns diameter starting with K 6-inch diameter tungsten wire ^^^^ Pre- sumably an arc process

A novel spherical Ti powder production method Granulation-Sinering-Deoxygenation (GSD) was invented and developed by a team led by Prof Fang for making low-cost spherical titanium and titanium alloy powders in 2015 GSD Ti powders can be used for near-net-shape (NNS) manufacturing methods including additive manufacturing (AM) metal injection molding (MIM) and hot-isostatic-pressing (HIP)

Submicron Spherical Tungsten Powder Prepared with

Violet tungsten oxide was prepared with pure ammonium paratungstate in argon gas Tungsten powder was obtained from violet tungsten oxide through deoxidation in hydrogen gas (rate of purity 99 99% dew point -40 C) and tungsten powder was oxidized in the air Tungsten oxide was reduced to tungsten powder in hydrogen gas The samples were characterized with the laser particle size distribution
