THERMAL INSULATION PROPERTIES OF SILICA AEROGELS: PROSPECTS FOR USE

Silica aerogels are unique highly porous materials with exceptionally low thermal conductivity, which opens up broad possibilities for their application in the field of thermal insulation. This article examines the main thermal insulation properties of silica aerogels, emphasizing their ability to effectively reduce heat transfer through conduction, convection, and radiation mechanisms. The physicochemical characteristics of aerogels are discussed, including porosity, density, pore size, and their influence on thermal conductivity. Special attention is given to the nanoscale structure of aerogels, which ensures their high efficiency in insulation. The study presents data on how changes in these parameters can lead to improved thermal insulation properties. The article also analyzes the prospects for using silica aerogels in construction, energy-saving technologies, and other industries where high thermal insulation efficiency is required. Potential areas of application are considered, including building insulation, the creation of energy-efficient systems, and use in specialized industrial conditions. The work discusses key factors affecting the thermal conductivity of aerogels, as well as current research and developments aimed at optimizing their properties for mass application. The conclusion emphasizes the importance of silica aerogels as materials of the future, contributing to the reduction of energy consumption and increasing the sustainability of structures.
