Porous Refractory Ceramics for High-Temperature Thermal Insulation - Part 1: The Science Behind Energy Saving

The article 'Porous Refractory Ceramics for High-Temperature Thermal Insulation - Part 1: The Science Behind Energy Saving' delves into the critical role of porous refractory ceramics in high-temperature thermal insulation. It begins by highlighting the urgent need for energy conservation due to climate change and the significant economic impact of related disasters. The text then focuses on the physical properties of porous ceramics, such as thermal linear variation, specific heat, and thermal conductivity and diffusivity, which are essential for their performance as thermal insulators. The article also explores the atomic origin of these properties and the various heat transfer mechanisms, including conduction, convection, and irradiation, that govern how heat moves through these materials. By understanding these mechanisms, professionals can better design and implement thermal insulation solutions to reduce energy consumption and mitigate the environmental impact of industrial processes.
