Product detail

Silicon Nitride (Si3N4) ceramic substrates are an advanced ceramic material that has excellent mechanical strength, high thermal shock resistance, and good chemical stability.  Si3N4 substrates are commonly used in high-temperature and high-stress environments, such as in gas turbines, automotive engines.  Additionally, Si3N4 ceramic substrates have good electrical insulation properties and can withstand high voltages, making them useful in high-power electronics applications.  Si3N4 substrates also have low thermal expansion, which makes them compatible with a wide range of materials, including semiconductors and metals.  These properties make Si3N4 ceramic substrates a popular choice for a variety of applications, including advanced electronics, aerospace, and automotive industries.

Mascera produces high quality silicon nitride substrates with customized sizes, standard thickness of 0.25mm, 0.385mm, 0.5mm, 0.635mm, 0.8mm, 1.0mm are selective for prompt delivery. No matter small orders for prototyping or bulk orders, we are always ready to offer our best service!

Main Properties of Silicon nitride 

1. High strength and toughness

Silicon nitride has a high fracture toughness and high flexural strength, making it suitable for applications that require high mechanical performance.

2.Low thermal expansion

Silicon nitride has a low coefficient of thermal expansion, which makes it resistant to thermal shock and thermal cycling.

3. High temperature resistance

Silicon nitride can withstand high temperatures up to 1200°C without significant deformation or degradation.

4. Good wear resistance

Silicon nitride has excellent wear resistance, making it suitable for applications that require high durability and resistance to abrasion.

5. Good electrical insulation

Silicon nitride is an excellent electrical insulator, making it suitable for applications that require electrical insulation and high temperature stability.

6. Low density

Silicon nitride has a low density compared to other ceramics, which makes it suitable for applications where weight reduction is important.

7. Chemical resistance

Silicon nitride is resistant to most acids and alkalis, and is chemically stable under a wide range of conditions.

8. Biocompatibility

Silicon nitride is biocompatible, which makes it suitable for medical and dental applications
