High vacuum hot press furnaces have a wide range of applications in the new materials industry, as follows:

1. Powder metallurgy: High vacuum hot press furnace is suitable for the field of powder metallurgy, used for hot press sintering of metal, ceramic, and refractory metal intermediate compound powders under high temperature and high vacuum conditions. By hot pressing sintering, the powder is rapidly densified, forming a dense polycrystalline sintered body with controllable microstructure, thereby improving the strength and properties of the material.

2. Functional ceramics: In the field of functional ceramics, high vacuum hot pressing furnaces are used for vacuum sintering of transparent ceramics, industrial ceramics, and other materials. A high vacuum environment helps to eliminate gases and impurities from materials, promote material densification, and improve the mechanical properties and stability of materials. For example, in the sintering of boron carbide ceramics, hot pressing sintering can strongly promote the densification rate and obtain materials close to physical and chemical density.

3. Hard alloy: High vacuum hot pressing furnace is also used for sintering hard alloy materials. During the sintering process, by applying pressure and maintaining a high vacuum degree, the sintering temperature can be reduced to prevent grain growth, resulting in finely grained and high-performance hard alloy products.

4. Target preparation: In the preparation of magnetron sputtering targets, high vacuum hot pressing furnaces play an important role. For metal or inorganic non-metallic target materials and composite target materials with significant differences in melting point and density, powder metallurgy combined with high vacuum hot pressing sintering can be used to prepare large-sized and high-density planar target materials.

5. Nanomaterials and Superconducting Materials: High vacuum hot pressing furnaces provide an ideal high-temperature and high vacuum environment for the production of nanomaterials and superconducting materials. In such an environment, materials can form and grow more cleanly, ensuring their excellent performance.
