Sintering is the last process of tungsten carbide production process, which is also the most basic and the most critical process. After sintering, the porous powder compacts turn into products with certain organization and performance. The sintering of tungsten carbide belongs to the powder metallurgy sintering process.

Vacuum Debinding and Sintering Furnace. Vacuum debinding and sinter furnace is mainly suitable for debinding and sinter process of tungsten alloy, heavy alloy, moly alloy, titanium alloy and cemented carbide materials. The vacuum debinding sitering furnace is used for PEG, paraffin and rubber binder removing.
Silicon carbide sintering furnace is mainly used in New materials reaction sintered silicon carbide. The maximum temperature is 1800C. With glue, dust removal system, complete evacuation and sintering meanwhile, silicon carbide sintering furnace has horizontal and vertical two types.
Preface: Tungsten Carbide, also referred as to Cemented Carbide, is manufactured by powder metallurgy methods. The tungsten carbide powders are mixed with a binder metal, which is normally cobalt or nickel in 3-28%, compacted in a die and then sintered in a furnace generally between 1350-1450︒C.
20161012PDF Furnace Elements. Carbosystem provides a wide variety of parts and refractory and calorific elements, used both in vacuum and sintering furnaces. For sintering furnaces are mainly used two types of technologies: (PM) for powder metallurgical processes, which use support trays and plates in graphite and mullite-cordierite.
August 2008 - Federal Carbide completes the installation of the most advanced sinter-HIP furnace in the world for the sintering of cemented tungsten carbide products. Further expanding its carbide sintering capabilities, Federal Carbide will place into service a new 12.5 cubic foot working capacity sinter-HIP furnace in August.
Sintering of binderless tungsten carbide - ScienceDirect . The activation energy is lowered for nano-scale powders, and hence a low sintering temperature is needed, and cemented carbide with better physical and mechanical properties can be obtained, .
Powder Metallurgy Vacuum Sintering Furnace takes high temperature vacuum sintering furnace is used in Sm-Co, AlNiCo, metal mesh, cemented carbide, ceramic materials, photoelectric coating materials, graphite purification, magnet material and rare refractory metals, alloys (tungsten, Mo, W-Cu alloy) vacuum sintering process, also support atmosphere sintering.
What is "Sintering or Sinter-HIPing"? Sintering is the process in which the tungsten carbide grains are fused into the cobalt matrix by heating the green material (carbide that has not been sintered is called green) to a high temperature.
Tungsten Powder Metallurgy - Sintering is commonly regarded as taking place in three stages： *During the early stage, necks are formed between individual particles and grow by diffusion, increasing the interparticle contact area. The powder aggregate shrinks, involving center to center approach of the particles.
The hydrogen used in the sintering equipment is to be recycled and the cooling water is to be used to heat other parts of the factory. The round and flat molybdenum and tungsten products are "baked" into high-strength blanks in the sintering plant, and are further processed into rods, wire, sheet and strip at Plansee.

Due to the extremely high melting point of tungsten carbide (≈2785 °C ), fully dense tungsten carbide bodies are extremely difficult to produce without the inclusion of an additive that will melt at far lower temperatures in order to cement the WC particles together to form a dense body. This process is known as sintering or, more
