Hello chemists

can anyone tell me the optimal temperature for metallic nanoparticles such as gold or silver upon annealing knowing that they are sensitive to higher temperatures
i want to know exactly the temperature to avoid agglomerations or deformation of shapes

best regards

I do not know the answer to your question, but would have to ask, if there is a critical temp for stability (which I did not know there was) - Is it independent of which metal is used, particle size and shape, surfactant types or anything else? I would be surprised if the optimum temperature for stability was independent of such things.
