Design Features

Custom silicon nitride ceramic blocks (also known as industrial ceramic insulating blocks) are designed for applications in extreme 

environments, especially those requiring high-temperature resistance and superior insulation.

High Temperature Resistance and Mechanical Strength

Silicon nitride ceramics exhibit high temperature resistance up to 1200℃, enabling them to maintain structural stability and functionality in a 

variety of high-temperature applications. Furthermore, their compressive strength reaches up to 2500 MPa, ensuring durability under high 

loads.

Excellent Thermal Management

With a thermal conductivity of 15-20 W/(m.K) and an extremely low coefficient of thermal expansion (3.1 x 10⁻⁶/℃), this material performs 

exceptionally well during thermal cycling, adapting to rapid temperature changes without easily breaking.

Electrical Insulation and Chemical Stability

Extremely high electrical insulation strength and good chemical stability make it particularly important in electronic manufacturing and 

chemical processing environments, resisting corrosion and maintaining performance.

Custom Design

Hole positions and shapes, such as center holes and other complex geometries, can be customized to specific application requirements, 

increasing assembly flexibility and versatility.

Application areas

Electronics Manufacturing

Used as an insulating layer or support structure to protect sensitive components during high-temperature processing in semiconductor 

manufacturing and other electronic component manufacturing.

High-Temperature Furnaces

Used in the internal structures of high-temperature furnaces, such as supports or thermal barriers, to improve temperature uniformity and 

reduce energy loss within the furnace.

Chemical Equipment

Used as corrosion-resistant and high-temperature insulating components in chemical reactors or processing systems.

Aerospace and Advanced Engineering Applications

Used in environments requiring extreme temperature and mechanical strength, such as thermal protection systems in spacecraft or 

components of high-speed machinery.
