The heat insulating material refers to a material having a thermal conductivity lower than 0.175 Wm-1K-1.
The special precipitated silica of the thermal insulation material has a large specific surface area, a high porosity and a low density. General Electric applied for the patent for this precipitation white carbon black application in 1987 and used it in insulation materials for domestic refrigerators and freezers. In recent years, many research institutions in China have conducted related research, mainly researching the synthesis technology and application technology of this kind of silica.
