Microwave
High-temperature
heating technology
The primary characteristics of High-Temperature Microwave Heating Technology are as follows:
Volumetric heating
-
Internal Heat Generation: Heat is generated directly within the material rather than being applied to the surface.
-
Rapid Heating: Since the process does not rely on traditional heat transfer (conduction or convection), heating speeds are exceptionally high.
-
Uniformity: Enables uniform heating even for thick or bulky materials.
Selective heating
-
Material Specificity: Energy is absorbed selectively by materials with high dielectric loss, allowing the target substance to heat while surrounding structures remain cool.
-
High Efficiency: Minimizes energy waste by heating only the necessary components.
Rapid Reach to High Temperatures
-
Extreme Temperatures: Materials with high microwave coupling efficiency—such as SiC, Carbon, and Metal Powders—can be heated to over 1,000°C.
-
Heating Rates: For powders at the micron scale or smaller, heating rates exceeding 100°C/min are achievable.
-
Ultra-High Temp: When combined with materials exhibiting ferroelectric properties at high temperatures, it is possible to reach temperatures above 2,000°C.
Fast Response and Controllability
-
Instantaneous Control: Immediate heating and cooling are possible via power ON/OFF cycles.
-
Process Precision: Excellent process controllability due to the ease of managing temperature ramp rates.
Non-Contact and Eco-Friendly Heating
-
Contamination Minimized: The absence of heaters or combustion sources minimizes the risk of oxidation and contamination.
-
Atmospheric Versatility: Heating can be performed within sealed systems, vacuum environments, or under reducing/inert gas atmospheres.
