Thermal insulators granules

After it is washed, dried, and granulated, this silica gel has a very high specific surface area (about 700 m2-g 1) and is useful as a drying agent, a support for catalysts, a packing for chromatography columns, and a thermal insulator. 

Several sintered glass and glass-ceramic matrix composites obtained from recycled silicate waste have been reported in the literature [100-106]. These are dense or porous products with potential application as building, decoration or architectural materials, such as wall partition blocks, pavements, wall and floor tiles, thermal insulation, fire protection elements, roofing granules and acoustic tiles. Other possible uses include abrasive media for blasting and polishing applications. 

Beds of aerogel granulate or powder are used for technical thermal insulation (Part 15), because they offer specific advantages in comparison to standard insulation materials, e.g., they can be poured into complicated shaped cavities. Opacified aerogel powders and granulates are used as thermal insulation in space applications [55], automotive applications...
