Joule Heating System

Product Detail

ACS Material LLC is pleased to introduce our advanced ultrafast joule heating (UJH) equipment, also referred to as flash joule heating or shockwave heating apparatus. This innovative approach enables the rapid heating of materials to exceptionally high temperatures within milliseconds. It works by passing a current through a resistive material, which rapidly converts the electricity to heat—thousands of Kelvins in 0~10 seconds. The FlashVolt™ Joule Heating System opens many exciting possibilities as it allows materials to be heated much faster and to extremely high temperatures than traditional methods. 

UJH has been used for many specialized applications, such as sintering ceramics, synthesizing metallic glasses, and welding carbon nanofibers. It’s also used to synthesize large-scale 2D materials, such as transition metal dichalcogenides, an emerging class of materials for use in transistors, solar cells, and catalyst applications.
