Abstract

High-temperature vacuum hot press sintering furnaces leverage the synergistic effects of high temperature, vacuum, and high pressure to produce high-density, high-performance materials. 

Their core applications focus on advanced ceramics and hard alloys:

● In advanced ceramics, they enable sintering of silicon nitride, silicon carbide, and aluminum nitride. The vacuum removes impurities, while high pressure ensures densification above 99%, meeting demands for structural strength and electronic insulation.
● In hard alloys, they sinter WC-Co alloys and ultra-hard coatings, prevent binder oxidation, and enhance hardness for cutting tools and drill bits.

Critical Role in Aerospace & Refractory Metals
This technology is vital for extreme-condition materials:
Aerospace: Sinters titanium-aluminum alloys and composites for brake discs, engine blades, and thermal protection parts—delivering strength, heat resistance, and corrosion resistance.
● Refractory Metals: Processes tungsten, molybdenum, and their compounds under vacuum to suppress volatilization, creating stable components like electron emitters and high-temperature molds.

Broad Industrial Applications
The furnace supports multiple high-tech sectors:
● Electronics: Semiconductor wafer carriers, ceramic substrates, and IC packaging for enhanced thermal and electrical performance.
● New Energy: High-thermal-conductivity ceramics for photovoltaics and optimized lithium battery cathode materials.
● Specialty Composites: SiC-reinforced aluminum matrices and ballistic materials, with high pressure ensuring uniform reinforcement dispersion.

By integrating advanced sintering into R&D and production, this equipment drives innovation across the high-performance materials supply chain.
