How to choose silicon nitride sheet correctly?

Silicon nitride sheet is a high-performance amorphous semiconductor material with advantages such as low loss, high reliability and high resistance to electromagnetic waves. Therefore, it is widely used in microwave materials, electronic materials, broadband applications and other fields. However, due to the special properties of silicon nitride sheet, people should pay attention when purchasing and using it.

What to pay attention to when purchasing and using silicon nitride

1. Physical

The physical properties of silicon nitride sheet are an important consideration, including the structure, tensile strength, compressive strength, bending strength, heat resistance, corrosion resistance, electrical insulation, etc. of the material. The appropriate physical properties should be selected according to the application requirements.

2. Electrical

The electrical properties of silicon nitride sheet are also an important consideration, including insulation resistance, dielectric constant, dielectric loss, capacitance, etc. Since the electrical properties of silicon nitride sheet directly affect its electronic properties in application, when selecting silicon nitride sheet, attention should also be paid to its electrical performance requirements.

3. Shaping

The shaping performance of silicon nitride sheet refers to its deformation after processing. Its shaping performance needs to be considered to ensure that it can meet the needs after processing.

4. Chemistry

The chemical properties of silicon nitride sheet refer to its durability in certain special environments. If the silicon nitride sheet will be used in a special environment, a sheet with good chemical properties should be selected to ensure its service life.

5. Price

You should also consider its price, because different sheets have different prices, and you should determine it according to your own needs and budget when purchasing. You should comprehensively consider its physical properties, electrical properties, shaping properties, chemical properties and prices to ensure that it can meet your own needs. Silicon nitride sheet is a new type of sheet made of a mixture of silicon and nitrogen elements. It has the advantages of excellent heat resistance, corrosion resistance, high strength and low thermal diffusivity. Therefore, silicon nitride sheet has been widely used in engineering, and its role is also multifaceted.

Advantages of silicon nitride sheet

1. Heat resistance

The heat resistance is relatively strong. It can withstand high temperature environments and can perform at its best in high temperature environments. Compared with general plastic sheets, the heat resistance of silicon nitride sheets is much higher, so it is used in high temperature environments such as metallurgical industry and oil refining.

2. Corrosion resistance

It also has good corrosion resistance, it can resist corrosive media such as sulfuric acid, hydrochloric acid, acetic acid, etc. Moreover, the corrosion resistance of silicon nitride sheet can also be improved by surface treatment technology, so that it can resist more corrosive media, thus better protecting.

3. High strength

It has good hardness and high strength, can resist the action of external forces, thereby protecting the machine. Silicon nitride sheet also has high thermal uniformity, reducing the temperature difference between equipment.

4. Low thermal diffusivity

The thermal diffusivity is very low, reducing heat emission, thereby saving energy. Moreover, the thermal stability of silicon nitride sheet is also very good, buffering heat energy, thereby protecting the machine.
