Product Description

This property is invaluable for maintaining structural integrity in a variety of applications. Silicon nitride is an excellent electrical insulator. It does not conduct electricity, which makes it useful in applications where electrical isolation is required.You can rest assured to buy Torbo® Si3n4 Plate from our factory and we will offer you the best after-sale service and timely delivery. Silicon nitride (Si3N4) is a ceramic compound composed of silicon and nitrogen atoms, characterized by mechanical, thermal and electrical properties. Silicon nitride has a high melting point and can withstand extreme temperatures, making it suitable for applications involving heat or high-temperature environments. Silicon nitride is known for its high mechanical strength and fracture resistance. A silicon rich silicon nitride substrate is a material used in electronic manufacturing. It is made of a thin layer of silicon nitride, which has a high resistance to electrical conductivity, and a high concentration of silicon atoms. This material is commonly used in the production of semiconductor devices, such as transistors and diodes, as well as optoelectronic devices, such as solar cells and light-emitting diodes (LEDs). The high concentration of silicon makes the substrates highly resistant to damage from ionizing radiation and temperature changes, which makes them ideal for use in space and high-temperature applications.

The Torbo® Si3n4 Plate

used in electronics fields such as power semiconductor modules, inverters and converters, replacing other insulating materials to increase production output and reduce size and weight. Double-sided heat dissipation in power cards (power semiconductors) , power control units for automobiles. Their extremely high strength also makes them a key material that increases the life and reliability of the products they are used in.

What is Si3n4 Plate?commonly used for? Silicon nitride is often used as an insulator and chemical barrier in manufacturing integrated circuits, to electrically isolate different structures or as an etch mask in bulk micromachining.

What are the disadvantages of silicon nitride? Unlike other ceramic materials, Silicon Nitride can hold similar loads to bearing steel; however, it is unsuitable for the race design in any application with shock loading due to the hardness of the material.


1. What are the advantages of using Si3n4 Plate?

Electronic substrates offer many benefits including a stable base for components, improved heat dissipation, and an easy-to-connect platform for circuits. They also provide durability and reliability in many applications.

2. How do I select the right Si3n4 Plate for my project?

The choice of electronic substrate will depend on the specific requirements of your project. Factors such as size, weight, temperature, and compatibility with other components will need to be considered. Consult with a supplier or engineer for guidance on selecting the appropriate substrate.

3. Can I create my own Si3n4 Plate?

It is possible to create your own electronic substrate, but it requires specialized knowledge and equipment. Unless you have the necessary experience, it is recommended to purchase ready-made substrates from a trusted supplier.
