Boric acid used to provide heat protection?

[ngilman]

Hi,

Has anyone heard of a layer of boric acid being used as a heat shield? I know it is often used in solution and other composites to act as a fire retardant, but what I'm looking for is any reference to boric acid, by itself, being used as an insulator. Maybe like a layer of boric acid protecting the components of a flight data recorder?

Heard of anything like this?

See US patent 6264854.

When was his query posted please ?

Hi there,

Yes, boric acid has been used as a heat shield in various applications. It has a high melting point and can withstand high temperatures, making it a good choice for heat protection. Some examples of its use include as a coating for spacecraft and as a flame retardant in building materials. It is also commonly used in the aerospace industry to protect sensitive equipment and components from extreme heat. In fact, boric acid is often mixed with other materials to create a thermal barrier for electronic devices and other heat-sensitive equipment. So, while it may not be used alone as a heat shield, it is definitely a key component in many heat protection systems.
