NANOTECH INC [US]
NANOTECH INC

Resumen de: MX2025008606A

A new and innovative hard ceramic coating having refractory properties is provided. The ceramic coating may be used as a replacement for refractory materials. As opposed to polymer-based coatings that are sacrificial when exposed to extreme temperatures, the ceramic coating is a non-sacrificial, fully inorganic (e.g., free of organic components) coating that resists many thermal cycles. The ceramic coating is also thinner and lighter than conventional refractory materials the ceramic coating can replace. The ceramic coating demonstrates advantageous thermal insulation properties (e.g., low thermal conductivity) over a wide range of temperatures and when applied with minimal thickness. The ceramic coating also demonstrates high emissivity, low thermal conductivity, and high resistance mechanical properties, which are all desirable properties for use as a thermally insulating replacement coating for refractory materials.
