The temperature is 0°C or higher. If the temperature exceeds 250°C, the crystal structure tends to develop and the amorphous property tends to become insufficient. Further, at temperatures below -40°C, the decomposition reaction is slow, resulting in a decrease in productivity.

I can't get metal. In addition, if a protic solvent, such as an alcohol, is used as a solvent, or if it is added to the solvent, a stable compound is formed with the metal in the solution, and precipitation does not occur, resulting in no metal powder or film.
