It is widely used in the pressureless sintering process of silicon carbide (SiSIC) ceramics. The silicon carbide products produced by the pressureless sintering furnace have better wear resistance, high temperature resistance and corrosion resistance. Efficient debinding/dusting device (with a new structure of air intake system).
High vacuum sintering furnace is mainly used in sinter cemented carbides, stainless steel line molding, stainless steel fiber, magnetic materials,and ceramic materials,and it also can be used in power metallurgy, refractory metals and magnetic material industry.
CX-SCSF series are top loading batch type induction heating furnaces with the maximum operating temperature of 2400℃.These furnaces operate with rough vacuum, partial pressure and micro-positive pressure of protective gases such as Argon and Nitrogen.Application: These furnace are suited for silicon carbide sintering,ceramic matrix composite sintering,transparent optical ceramic sintering,C
Liquid phase sintering is used to densify silicon carbide based ceramics using a compound comprising a rare earth oxide and aluminum oxide to form liquids at temperatures in excess of 1600° C. The resulting sintered ceramic body has a density greater than 95% of its theoretical density and hardness in excess of 23 GPa.
The properties and preparation route of silicon carbide- and boron carbide-based materials is described extensively in Ref.  These composites combine good thermal shock resistance and oxidation resistance. The typical processing route involves pressureless sintering followed by posthiping to pro-duce dense SiC-B

Selecting the Right Vacuum Furnace for the Job - Vacaero . The features necessary for a particular vacuum furnace to run a specific heat treatment process are often determined by results one wishes to achieve, the type and geometry of the component parts to be run (Fig. 3 - 4), the productivity requirements, the physical size of the load, the pressure and temperature to be attained, and the
This process starts with molten silicon encasing solid carbon followed by reactive wetting to form silicon carbide. Reaction sintering of silicon carbide from a mixture of silicon and carbon powder in slurry form was conducted using high-frequency, pulsed laser as heat source.
20191010Pressureless silver (Ag) sintering was optimized at 250°C in vacuum and nitrogen gas atmosphere with silicon carbide (SiC) chips, and silicon nitride active metal-brazed substrates (AMB). A 1200-V/200-A power module was developed using a pressureless Ag-sintered live SiC metal-oxide-semiconductor field-effect transistor (MOSFET) device and
After machining the silicon carbide blocks are sintered at high temperature in a vacuum furnace. SE type silicon carbide block Our SE SiC blocks are made of pressureless sintered SiC thus guarantying their outstanding corrosion resistance.
Pressureless sintered silicon carbide (SSiC) is made of high-purity and ultra-fine silicon carbide powder, and a small amount of sintering aid, such as boron, carbon, etc., is sintered in an inert gas or vacuum atmosphere at atmospheric pressure at a high temperature of 1950~2100 °C.
Vacuum Sintering Furnaces The vacuum sintering furnace is a vacuum resistance furnace using graphite as a heating element. The special carbide, nitride and oxide ceramics are sintered into a product in a vacuum or a protective atmosphere, and can also be used for heat treatment of metal materials.
Reaction bonded silicon carbide SiSiC (e.g. axial face seals, composite materials, kiln furniture etc.) Pressureless sintered silicon carbide (parts for high performance applications at high temperatures or in severe environments). Hard metals (WC, TaC, TiC, NbC) with a metallic "binder" such as Co or Ni.
