Borosilicate glass can easily handle most lab temperatures, and can handle 400°C for short-term service, typically 200-230°C for normal, standard use service. How Borosilicate glass can be used inside the furnace, where the temperature is 500°C .

Hi sir your explanation is so satisfying I have nanoparticle synthesis by organic method for my desertation can give me some suggestions regarding it which can be done in lab with less facilities and low cost

Interesting, Can you share the first metal oxide prepared using Low temperature Combustion method. Kindly share the paper title (or DOI link ) by Prof. K.C. Patil

Sir, during the reaction is the muffle furnace must be in open condition at 500 deg. Celsius

Very useful video, Sir What about time of keeping in muffle furnace? And temperature rate increasing?

because of exothermic redox reaction between metal nitrate(oxidant) and fuel (reductant).
