Boric acid used to provide heat protection?

AI Thread Summary
Boric acid is being explored as a potential heat shield, particularly in applications like protecting flight data recorders. While it is commonly used in solutions and composites for its fire-retardant properties, the discussion centers on its effectiveness as a standalone insulator. The query references US patent 6264854, which may provide insights into its application in this context. The conversation seeks any existing references or studies that support the use of boric acid in this capacity.

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?

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
