The diatomaceous earth is used for insulating boilers and steam pipes ...
Cells of diatoms are surrounded by the cell wall, deposited with silica called as frustules which are composed of two overlapping halves (the epitheca and the hypotheca). Shells of diatoms are highly resistant to decomposition due to the presence of silica and are deposited in ocean beds leading to the formation of the diatomaceous earth. This is used as filters because its silica content makes it chemically inactive and uncompressible during insulation.

Insulating properties of diatomaceous earth:
- Thermal conductivity:
Diatomaceous earth is a poor conductor of heat. This property makes it an excellent insulating material for boilers and steam pipes. When used to insulate these systems, it helps prevent heat loss, improves energy efficiency, and maintains the temperature of the steam within the pipes.
- Air pockets:
Diatomaceous earth consists of tiny particles that create air pockets within the material. These air pockets act as barriers to the transfer of heat, further enhancing its insulating properties. The presence of these air pockets helps to trap heat and prevent it from escaping, making diatomaceous earth an effective insulator.
- Chemical composition:
Diatomaceous earth is primarily composed of silica, which is a poor conductor of heat. This composition contributes to its low thermal conductivity and makes it an ideal material for insulation purposes. Additionally, diatomaceous earth is lightweight and easy to handle, making it a practical choice for insulating boilers and steam pipes.
In conclusion, the use of diatomaceous earth as an insulating material for boilers and steam pipes is primarily due to its low thermal conductivity, the presence of air pockets, and its chemical composition. These factors work together to make diatomaceous earth an effective insulator that helps to improve energy efficiency and maintain optimal temperatures in industrial systems.

Because diatomaceous earth is a soap box like structure made up of SILICA and silica is a bad Conductor of heat...it is that simple :)
