How long does it takes for a sample to cool in box furnace?

12 July 2020 0 8K Report

Hi,

I am preparing nanotubes of graphitic carbon nitride g-C3N4. One very important step in its synthesis involves annealing for which I have to place my vaccum dried sample in a box furnace and heat it at a rate of 8°C/min to 350°C for 1h. Since annealing involves furnace cooling, how long should it take my sample to cool?
