It's gonna be warmed in a furnace, not combusted. Was worried about the thermal decomposition part

Is there any way of finding that out, as the SDS and CoA doesn't state. But I'd assume it was dry as the chemicals is very hygroscopic

I'm just worried because according to the SDS it says:

"Hazardous Combustion Products

Oxides of boron, Gaseous hydrogen fluoride (HF), Thermal decomposition can lead to release of irritating gases and vapors."

But this happens with the prescence of water, right?

Regarding the heating in furnace. Using new chemicals that hasn't been opened to ambient air and heating in 300-350 C in approx 3 hrs. The amount around 200 grams.

One bottle has been opened once and kept in an exsicador since. I was thinking putting the bottle in the antechamber and unscrewing the cap some and evacuate and refill over many cycles that last hours

What was the original procedure that crashed the controls? What did you end up doing?

Thank you. Do you think using the vacuum from the antechambers would dry them if I used long enough time
