Product Description Product DescriptionA vacuum sintering furnace is a complete set of equipment used for sintering materials into shape under vacuum or inert atmosphere conditions, employing resistance heating.It is primarily applied in the sintering of metallic materials such as powder metallurgy, hard alloys, copper, tungsten, titanium alloys, as well as ceramics and powder materials.Applications Powder Metallurgy Powder metallurgy is one of the core application areas for vacuum sintering furnaces. Metal powders are pressed and formed, then sintered in a vacuum environment to achieve bonding and densification of the powder particles.Structural Parts: Such as gears, bearings, and cams used in automobiles and motorcycles. Vacuum sintering reduces porosity and impurities in the parts, enhancing their strength and wear resistance.Refractory Metal Products: Metals like tungsten, molybdenum, and tantalum have extremely high melting points and are prone to oxidation when sintered in air. Vacuum sintering ensures their purity and performance, used for manufacturing high-temperature furnace components and electron tube electrodes.Hard Alloys: Hard alloy tools and molds made from carbides like tungsten carbide and titanium carbide, bonded with cobalt, benefit from vacuum sintering to avoid oxidation of the binder, improving the alloy's hardness and toughness.Aerospace Aerospace materials demand stringent performance requirements. Vacuum sintering furnaces are used to prepare key components with high strength, heat resistance, and corrosion resistance.High-Temperature Alloy Components: Turbine blades and combustion chambers require operation under high-temperature and high-pressure conditions. High-temperature alloys (e.g., nickel-based alloys) produced via vacuum sintering exhibit excellent high-temperature strength and oxidation resistance.Titanium Alloy Components: Titanium alloys possess high strength and low density but react with oxygen and nitrogen in the air. Vacuum sintering produces high-purity, stable-performance titanium alloy structural parts for aircraft fuselages and engine components.Ceramic Matrix Composites: Such as silicon carbide ceramic composites, vacuum sintering eliminates internal defects, enhancing their heat resistance and thermal shock resistance for use in spacecraft thermal protection systems.Electronics and Semiconductors Vacuum sintering furnaces ensure stable electrical properties in the preparation of electronic components and semiconductor materials.Electronic Ceramics: Capacitor ceramics and piezoelectric ceramics benefit from vacuum sintering for precise control of ceramic composition and microstructure, ensuring compliance with dielectric constant and piezoelectric performance standards.Semiconductor Materials: Sintering and diffusion processes for semiconductor materials like silicon wafers and gallium arsenide often require a vacuum environment to prevent impurity contamination and enhance electrical performance.Metallization Layer Preparation: When preparing metallization layers (e.g., molybdenum-manganese metallization) on ceramic or semiconductor substrates, vacuum sintering promotes bonding between the metal and substrate, ensuring conductivity and adhesion of the coating.Medical Devices Medical devices demand high biocompatibility, precision, and cleanliness. Vacuum sintering furnaces are used to produce various medical components.Implantable Metal Devices: Artificial joints and bone screws, commonly made from titanium alloys or stainless steel, undergo vacuum sintering to remove harmful impurities and reduce rejection reactions after implantation.Dental Materials: Porcelain teeth and dental alloy brackets benefit from vacuum sintering to ensure material strength and aesthetics while avoiding performance degradation due to oxidation.Medical Blades: Precision blades like surgical scalpel blades achieve enhanced sharpness and durability through vacuum sintering, with a cleaner surface.New Energy In the preparation of new energy materials, vacuum sintering furnaces enhance energy density and cycling performance.Lithium Battery Materials: Sintering processes for positive electrode materials (e.g., ternary materials, lithium iron phosphate) and negative electrode materials ( e.g., graphite) require vacuum or inert atmosphere conditions to prevent oxidation and improve electrochemical performance.Fuel Cell Components: Vacuum sintering ensures the porosity and conductivity of fuel cell electrodes and electrolyte membranes, enhancing battery efficiency.Solar Cell Materials: For certain thin-film solar cell electrodes or absorbing layer materials, vacuum sintering optimizes crystallinity and electrical properties.Research and New Material Development Vacuum sintering furnaces are essential equipment for research institutions engaged in new material development, enabling exploration of novel material preparation processes and properties.Research on the effects of different vacuum levels, temperature profiles, and holding times on material structure and properties provides data support for the industrial production of new materials.Development of sintering technologies for novel materials such as nanomaterials, amorphous alloys, and intermetallic compounds expands material applications.Product Parameters Product NameVacuum Sintering FurnaceRated Voltage0-75VPower Supply VoltageThree-phase 380VRated Power30KWMaximum Temperature1600oC, 1800oC, 2000oC, 2200oCUltimate Vacuum at Cold State6.67*10^-3 PaWorking Zone Dimensionsφ200mm x Height 200mm (customizable)Pressure Rise Rate≤4.0 Pa/hHeating MaterialMolybdenum-Tungsten, GraphiteTemperature Control RangeRoom Temperature - 1600oCTemperature Control Accuracy±1oCCharging Pressure≤0.03 MPaCharging MediumInert Gases such as N2, ArDetailed Photos
