Dielectric heating is a process that uses high-frequency electromagnetic fields to heat materials, particularly non-conductive substances like plastics and ceramics. This method works by causing polar molecules within the material to rotate and align with the alternating electric field, generating heat through molecular friction. Commonly used in industrial applications, dielectric heating is effective for drying, curing, and bonding materials. It is also utilized in consumer products, such as microwave ovens, where it heats food by agitating water molecules. This technology offers efficient and uniform heating, making it valuable in various manufacturing processes.
