The time for sintering nitrides in a customized vacuum sintering furnace varies due to various factors, including the type of nitride, sintering temperature, sintering pressure, and desired sintering effect. Generally speaking, the sintering time can range from a few minutes to several tens of hours.

For example, in certain specific processes, the sintering time may only be a few minutes or hours, such as using rapid sintering techniques or specific sintering curves. In other cases, if highly dense and uniform nitride materials are required, the sintering time may be longer, even up to several tens of hours.

Specifically, the sintering time for nitrides such as aluminum nitride (AlN) or silicon nitride (Si ∝ N ₄) may also vary. Usually, the sintering of these materials needs to be carried out at high temperatures and may require segmented sintering, that is, low-temperature pre sintering followed by high-temperature sintering, to optimize the properties of the materials.

In addition, the sintering time may also be affected by factors such as the heating rate, cooling rate, and holding time of the sintering furnace. Therefore, when customizing a vacuum sintering furnace for nitride sintering, the sintering time needs to be determined based on specific material characteristics and process requirements.

Overall, it is not possible to provide a fixed sintering time as it needs to be adjusted according to the actual situation. In practical operation, it is usually necessary to determine the optimal sintering time and process parameters through experiments to obtain the desired properties of nitride materials.
