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?
