Vacuum sintering furnace is a device that can prepare high-quality metal and ceramic materials, and its usage skills are very important for the impact of sintering effect. Therefore, when using a vacuum sintering furnace, special attention should be paid to the following points:

1.Control the vacuum level

Vacuum degree is an important parameter in a vacuum sintering furnace, which has a significant impact on the sintering effect. Therefore, when using a vacuum sintering furnace, attention must be paid to controlling the vacuum degree to ensure that the vacuum degree is between 10^-5-10^-6Pa.

2.Control temperature

Temperature is an important parameter when sintering materials in the vacuum sintering furnace. It is necessary to maintain a reasonable sintering temperature and pay attention to the sintering heating rate to ensure the physical properties, chemical stability and structural properties of materials.

3.Heating method

The vacuum sintering furnace mainly uses methods such as resistance heating, inductance heating, and radiation heating for heating. When using it, appropriate heating methods should be selected according to the material requirements, and attention should be paid to maintaining uniformity.

4.Sintering medium

When using vacuum sintering furnace, it is necessary to select appropriate sintering media according to the properties of sintering materials, generally including inert gas, nitrogen, argon and hydrogen.

5.Loading method

When using a vacuum sintering furnace, attention should be paid to the material loading method to ensure uniform stacking of materials, and attention should be paid to sealing to prevent gas leakage.

6.Sintering time

The sintering time is generally determined based on the specific situation of the material, but should be controlled within a reasonable range to ensure a uniform sintering effect.

7.Cooling method

After completing vacuum sintering, inert gas or nitrogen should be used for cooling to avoid unnecessary reactions or changes in the material.

The above are some tips for using a vacuum sintering furnace. If these techniques can be used correctly, not only the preparation efficiency and quality of vacuum sintering furnace can be improved, but also the physical properties, chemical stability and structural properties of sintered materials can be better guaranteed.
