Vacuum sintering Traditional, still much used. HIP-treatment (Hot Isostatic Pressure) The main and future method for hard metal industry. In HIP-treatment Tungsten Carbide is sintered in a furnace under high gas pressure. All porosity is possible to eliminate from Tungsten Carbide.
Operation in Inert gas, Hydrogen Process gas, or vacuum environment. Two-sided or four-sided graphite heating elements and durable Graphite Board insulation for long hot zone life. Cold wall design offers rapid heat up and cool down times (2-3 hours from RT - 2200°C) compared with 3-5 days for heat-up/cool-down of refractory hot wall units.
Description: Platinum thermocouple assemblies with support tubes for limit and control. Used in a vacuum-environment, heat-treat furnace with inert-gas purge. Tungsten-rhenium Type C assemblies with sintered alpha silicon carbide sheath tubewell for use in semiconductor sintering applications Sensor Type: Temperature Probe
Tungsten powder is blended with carbon (lampblack) and converted to tungsten carbide usually in induction furnaces at temperatures from 1300 to 1500° C (2400 to 2800° F). The sintering operations can be conducted in either resistance or induction type furnaces of stainless steel construction and water cooled.
The alloy is intended for use in fluxless atmosphere (reducing or inert gas) or vacuum brazing applications. Argo-braze™ 63V is, however, prone to liquate (separate into low and high melting constituents) if it is heated slowly through its melting range. For this reason rapid heating methods should be employed wherever possible.
200387The precursor materials are then heated and reacted in a controlled temperature furnace under either vacuum or an inert atmosphere such as argon gas to synthesise titanium carbide. Alternatively heating under a nitrogen atmosphere will enable the synthesis of titanium nitride.
Joints using Active-braze™ No.15 need to be brazed under vacuum or high purity, low dew point inert gas. Brazing can be carried out in furnaces with vacuum or inert gas atmospheres or using HF Induction heating under vacuum or inert gas. Vacuum conditions: 1 x 10-4 torr or better with a leak rate of less than 5 microns an hour. As the brazing
Product application: it mainly used for the preparation of rare earth, electronic lighting, crystal annealing, biological ceramics, electronic ceramics, special alloy, magnetic materials, precision casting, vacuum sintering of metal heat treatment and other industries, protective atmosphere sintering, vacuum coating, CVD experimental measurement, material composition, etc.
Vacuum aluminum brazing (VAB) is per-formed in a vacuum furnace and is considered fluxless brazing because flux is not used to cre-ate joints. Fluxless brazing processes can be performed using inert gas atmospheres or in vacuum furnaces. Application examples in-clude semiconductor manufacturing and ce-ramic to copper brazing. Due to the vacuum's

The vacuum subsequent hot isostatic pressing process is a hot isostatic pressing of the product after conventional vacuum sintering, and the sintered product is sintered to a product having a density higher than 92% theoretical density, and the pressure is 80-150 MPa, and the inert gas is The pressurized medium is treated in a hot isostatic
2. Vacuum furnace can prevent the oxidation of molten raw materials and prevent the incorporation of impurities. The device is suitable for the casting of high purity metal materials or easily oxidized elemental metals. 3. Melting in an inert gas atmosphere, oxidation loss of carbonaceous ruthenium, etc. is extremely small. 4.
Today these AVS specialty furnaces dominate the tungsten carbide sintering furnace market. Using specialized vacuum pumping systems, binder traps and condensers, plus engineered gas delivery systems, AVS Sinter HIP furnaces provide closely controlled vacuum, partial pressure and HIP atmosphere control from vacuum to 150 bar and higher.
