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

1. Physics

The physical properties of silicon nitride sheets are an important consideration, including the structure of the material, tensile strength, compressive strength, bending strength, heat resistance, corrosion resistance, electrical insulation, etc. Choose the appropriate physical properties according to your own application requirements.

2. Electricity

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

3. Shape

The shape-setting performance of the silicon nitride sheet refers to its deformation after processing, and its shape-setting performance needs to be considered to ensure that it can meet the requirements after processing.

4. Chemistry

The chemical properties of silicon nitride sheets refer to their durability in some special environments. If the silicon nitride plate is to be used in a special environment, the plate with good chemical properties is required to ensure its service life.

5. Price

The price should also be considered, because different boards have different prices, which should be determined according to their own needs and budget when purchasing. It is necessary to comprehensively consider its physical properties, electrical properties, setting properties, chemical properties and price, etc., to ensure that it can meet its own requirements. Silicon nitride plate is a new type of plate composed of silicon and nitrogen elements. It has 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.

1. Heat resistance

Heat resistance is relatively strong, it can withstand high temperature environment, and can play the best performance in high temperature environment. Compared with ordinary plastic sheets, silicon nitride sheets have much higher heat resistance, so they are used in high-temperature environments such as metallurgical industries and oil refining.

2. Corrosion resistance

Also has good corrosion resistance, it can resist corrosive media, such as sulfuric acid, hydrochloric acid, acetic acid, etc. Moreover, the corrosion resistance of the silicon nitride plate can also be improved through surface treatment technology, so that it can resist more corrosive media, so as to better protect.

3. High strength

With good hardness and high strength, it can resist external force, thereby protecting the machine. The silicon nitride plate also has high thermal uniformity, reducing the temperature difference between equipment.

4. Low thermal diffusivity

The thermal diffusivity is very low, which reduces heat emission and thus saves energy. Moreover, the thermal stability of the silicon nitride plate is also very good, which can buffer heat energy and protect the machine.
