Home ProductsJoule heating device series

Joule heating device Max 3000℃

Product introduction

The Joule heating device utilizes the phenomenon of the Joule effect of conductive materials themselves to apply an electrical environment, resulting in the material reaching extremely high temperatures (1000-3000 ℃) in a very short time (0-10 S), in order to investigate the physical properties changes of the material under extreme environmental and severe thermal shock conditions.

This product can provide an electrical environment for conductive and non-conductive materials and measure their temperature, with a temperature measurement range of 250~3000 ℃; This product is currently widely used in fields such as batteries, catalysis, ceramics, metal materials, etc. It can prepare nanoscale particles, single atom catalysts, high entropy alloys, etc. through rapid temperature rise and fall; The device can be customized for electrical environments and vacuum systems. Accessories include: control cabinet, vacuum chamber, electrode, vacuum pump, high-temperature sample stage, temperature measuring probe, and adapter cable.

Application case

Analysis of the Results of Biocarbon Flash Preparation of Graphene

The following figure is a comparison of Raman spectra between graphite and graphene. It can be seen whether it is graphene, and the key is to look at the 2D peak

The absence of a D peak indicates low impurities. When using 2D/G to measure the number of graphene layers, less than 1 indicates multiple layers, equal to 1 indicates double layers, and greater than 1 indicates single layers.
Our experimental results are as follows (prepared at 3000k):
