Because the melting point of manganese nitride is relatively high, it is generally synthesized or processed at high temperatures. Therefore, when using manganese nitride, it needs to be heated to a temperature above the melting point to ensure its complete melting. Manganese nitride has a high melting point and hardness, and it is necessary to take appropriate protective measures, such as wearing masks, gloves and goggles, to avoid harm to the human body.

 

In the synthesis of manganese nitride, it is usually necessary to add some metal or non-metallic elements as alloying elements to adjust its physical and chemical properties. These alloying elements can be selected and adjusted as needed to obtain the desired properties.

 

For some temporarily unused manganese nitride, it needs to be stored in a dry and ventilated place, and to avoid contact with water vapor to prevent moisture absorption.

In the process of using manganese nitride, it is necessary to avoid collision with hard objects or scratching the surface to avoid damage. Also avoid contact with oxygen in the air to prevent oxidation deterioration. In addition, it is necessary to control the temperature and time to prevent volatilization loss.

 

The use method of manganese nitride needs to be adjusted and selected according to the specific application scenarios and needs, and the precautions are to ensure its safety and stability during use.

 

How to improve the performance of manganese nitride in smelting

Manganese nitride is a compound composed of manganese and nitrogen that has a solid crystal structure and is black or gray solid. In the preparation process of manganese nitride, ammonia high-temperature decomposition and nitriding method need to add residual ammonia absorption device. The nitrogen generated by ammonia decomposition is highly active, so the nitriding efficiency is high. However, in the smelting process of manganese nitride, the following methods can be used to improve the performance of manganese nitride.

 

Optimization of smelting process:

By optimizing the smelting process of manganese nitride, the phase composition, particle size and morphology of manganese nitride can be controlled, thereby improving its performance. For example, the high temperature and high pressure nitriding process can be used to increase the pressure and temperature of nitrogen, and promote the diffusion and adsorption of nitrogen atoms on the metal surface, so as to prepare high-performance manganese nitride materials.

 

Control of nitriding temperature and time:

nitriding temperature and time are important factors affecting the performance of manganese nitride. In a certain temperature range, the phase composition and stability of manganese nitride can be improved by increasing the nitriding temperature and extending the nitriding time. However, too high temperature and too long time will lead to changes in the structure of manganese nitride, performance is reduced. Therefore, it is necessary to control the nitriding temperature and time reasonably.

Adding alloying elements:

By adding alloying elements to manganese nitride, parameters such as phase composition, structure and morphology can be changed to improve its performance. For example, adding titanium to manganese nitride can improve its oxidation resistance and high temperature stability; Adding iron to manganese nitride can improve its magnetic properties and stability.

 

Surface treatment:

Surface treatment is a way to improve the properties of manganese nitride. The surface structure and morphology of manganese nitride can be changed by surface coating, coating and coating, and its oxidation resistance, corrosion resistance and wear resistance can be improved. For example, plasma spraying technology can be used to prepare a ceramic coating on the surface of manganese nitride to improve its oxidation resistance and high temperature stability.

 

In general, improving the performance of manganese nitride requires comprehensive consideration and optimization from the aspects of smelting process, temperature and time control, alloying element addition and surface treatment. The application of these methods can improve the performance of manganese nitride and expand its application field.
