Ultra-fast Joule Heating Furnace UHS-3000, temperatures up to 3000°C
- Product Description
-
Joule Heating Furnace UHS-3000 is a versatile, next-generation rapid ultra-high-temperature sintering device. By employing Joule heating of electrically conductive carbon materials to generate a high-temperature field, it achieves ultra-fast heating and cooling rates as well as extremely high sintering temperatures, enabling the rapid synthesis and sintering of materials within just a few minutes. This approach effectively suppresses the high-temperature volatilization of low-melting-point constituents, minimizes side reactions and interdiffusion, inhibits grain growth, and facilitates the fabrication of materials with complex geometries. It finds broad applications in ceramic materials, solid-state electrolytes, oxide fuel cell materials, metal nanocatalysts, graphene, and other fields.
Superior Performance:
◆ Advanced carbon heater: supports up to 3,000°C
◆Ultra-fast heating rate: 10–500°C/s
◆ Millisecond-level pulsed heating
◆Custom program temperature control
Application areas:
♦ Ceramic synthesis: At a high temperature of 3000°C, dense ceramic compacts can be rapidly sintered within approximately 10 seconds, making this process suitable for various ceramic synthesis applications, as it minimizes volatilization and enhances densification.
♦ Solid electrolyte: The material is heated to 1773 K within 6 seconds, held at this temperature for 10 seconds, and then rapidly cooled over another 6 seconds, enabling ultrafast sintering and the synthesis of novel garnet-type solid-state electrolytes (SSEs). This process minimizes lithium loss, achieves a relative density of approximately 92%, and ensures high material purity and outstanding electrochemical performance.
♦ Alloy Catalysis : Rapid heating to 1074 K within 2 seconds via Joule heating induces the formation of a PtCoCu alloy on a carbon nanotube (CNT) matrix, yielding a highly efficient ternary Pt–Co–Cu catalyst for the electrocatalytic oxidation of ethanol (EOR).
