Microwave & Inductive Heating


Microwave and induction heating are precision electrification technologies that deliver high efficiency, rapid heating, and fine process control across a wide range of industrial applications. Unlike rotary kilns and calciners, which provide bulk continuous thermal treatment, microwave and induction systems are often used for batch or specialty processing steps where temperature ramp rates, uniformity, or localized heating are critical. These solutions are increasingly important in battery materials, semiconductors, specialty metallurgy, and advanced ceramics, as industries transition from fossil-fired thermal systems to fully electrified alternatives.

Both methods eliminate combustion-based heat sources: induction heating uses alternating electromagnetic fields to heat conductive materials directly, while microwave systems excite polar molecules to generate volumetric heat inside the material. This provides higher energy efficiency, lower emissions, and faster cycle times, aligning with the goals of industrial electrification.


Electrified Process Chain

Process Step Technology Role Electrification Advantage
Ore & Material Drying Microwave dryers Removes moisture from ores, powders, and precursors Faster, more uniform drying vs fossil-fired rotary dryers
Battery Material Processing Microwave & induction calciners Calcination and surface treatments of cathode/anode powders Precision control improves CAM performance, lower energy demand
Semiconductor Crystal Growth Induction-heated crystal pullers Melts polysilicon and maintains precise thermal gradients High purity, fine temperature control essential for wafer quality
Metal Forging & Heat Treatment Induction furnaces, induction hardening systems Heats and hardens metals for forging, annealing, or welding Direct electrical heating, efficient, eliminates fossil fuels
Advanced Ceramics & Glass Microwave sintering systems Sintering and densification of ceramics and specialty glasses Volumetric heating reduces cycle times, improves uniformity

Role in Industrial Electrification

  • Provides an alternative to fossil-fired kilns and resistive heating with higher efficiency and faster cycle times.
  • Enables electrification of precision, batch, and specialty processes across mining, batteries, semiconductors, and metals.
  • Reduces direct emissions and enables integration with renewable-powered grids and onsite BESS.
  • Complementary to rotary kilns/calcination: kilns serve bulk throughput, while microwave and induction systems serve high-value precision applications.
