Prepare raw materials
The raw materials required to produce nickel silicide are mainly elemental nickel powder and elemental silicon powder, as well as an appropriate amount of catalyst and protective gas. These raw materials must be processed and prepared to ensure smooth progress.
Mix raw materials
The elemental nickel and silicon powder are mixed proportionately to form a uniform mixture. This mixing process ensures the two raw materials are in sufficient contact to facilitate the subsequent synthesis reaction.
High-temperature synthesis
Put the mixed raw materials into a high-temperature furnace and react at about 1000 ° C or more. A chemical reaction occurs between nickel and silicon powder to form nickel silicide. This process needs to control the temperature and reaction time to ensure that the resulting nickel silicide product has excellent quality and stability.
Commonly used catalysts include metal elements, metal oxides, etc. By adding the trigger, the reaction temperature and reaction time can be reduced, thus improving the production efficiency.
Cooling and grinding
After the high-temperature synthesis reaction is completed, the resulting nickel silicide needs to undergo a process of cooling and grinding. This step is to cool the nickel silicide from its high-temperature state and make the necessary particle size adjustments and grinding to meet the needs of different application areas.
Surface treatment
It is sometimes necessary to treat the surface of nickel silicide. This can be achieved by coating, coating, and other methods, according to the application field and actual needs to choose the appropriate surface treatment method.
Packaging and storage
After cooling, grinding, and surface treatment, nickel silicide products must be packaged and stored. When packaging, it is necessary to pay attention to prevent the development from being damp, prevent impurities from being mixed, etc., and periodically check the quality and particle size distribution of the product when storing to ensure that the product meets the requirements.
Recycle and dispose of waste
The production process will produce some waste, such as an incomplete reaction of nickel and silicon powder. These wastes need to be appropriately disposed of to avoid causing pollution to the environment. Standard treatment methods include recycling, landfill, incineration, etc.
