Silar® Microwave Absorbent Ceramics
Silar® Microwave Absorbent Ceramics are a unique class of ceramic materials that deliver results in a wide range of microwave applications, such as:
- Microwave cooking, food processing, cookware
- Industrial microwave heating
- Microwave drying and curing of materials with low water content
- Microwave melting of metals
- Safety and control devices for microwave ovens.
Silicon carbide can absorb microwave radiation. However, there are over 400 known types of silicon carbide. Some types do not absorb microwaves at all, others are minimal absorbers. Most types vary in their absorption, being able to absorb only at elevated temperatures, i.e., above 500°C. As a result, silicon carbide has historically found limited use in microwave applications.
ACM, LLC synthesizes Silar® single crystal silicon carbide that has a unique polytype crystalline structure with remarkable microwave properties. ACM, LLC also makes Silar® ceramic composites for a wide range of applications. A material cross-section is depicted below:
Combining an engineered ceramic matrix and Silar® crystals yields a high-tech composite with a high loss tangent that heats rapidly in a microwave field, withstands very high temperatures, has high strength and crack resistance, and is thermal shock resistant.
