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?

Hi there,

Yes, boric acid has been used as a heat shield in various applications. In fact, it is commonly used as a flame retardant in products such as insulation, textiles, and electronics. It has a high melting point and can withstand high temperatures, making it a suitable material for heat protection.

As for its use as a layer to protect flight data recorders, I was able to find a few references to this in aviation forums and discussions. It seems that boric acid powder has been used in some cases to protect the sensitive components of flight data recorders from extreme temperatures during a crash or fire. However, it is important to note that this is not a standard practice and the use of boric acid in this way may vary depending on the specific circumstances and regulations of the aviation industry.

I hope this helps answer your question. Thank you for bringing up this interesting topic!
