Excellent Thermal Conductivity Silicon Nitride Components Si₃N₄ Solid Structural Ceramic Substrates

Thermal Conductivity Silicon Nitride Ceramic Block Si₃N₄ Solid Substrates for High‑Temperature Application


Thermal Conductivity Silicon Nitride Substrates

Ceramic substrates are a type of advanced ceramic material used to provide a stable base for components in automotive, electronic, and industrial applications. The substrate typically has a flat, rectangular shape, with a smooth and uniform surface. It is made of a ceramic material such as alumina or silicon carbide, which has promising mechanical, thermal, and electrical properties.

Our Silicon nitride substrate features high thermal conductivity, outstanding mechanical strength, excellent thermal shock resistance and low thermal expansion coefficient. It is widely adopted for power electronic packaging such as IGBT modules, new energy vehicle power devices. Custom cutting, laser drilling and grooving are available according to drawings.


Si3N4 Ceramic Parts are a man made compound synthesized through several different chemical reaction methods. they are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.


■ Impressive Thermal Performance

These ceramic materials have a low thermal expansion coefficient and high thermal conductivity, which could increase the efficiency of components and reduce the possibility of heat damage. For instance, the thermal conductivity of SiC is no less than that of metals.
■ Remarkable Electrical Features
With higher electrical conductivity, chips and other components based on ceramic substrates use less energy, and the signal delay time can be reduced.
■ Superior Thermal Shock Resistance
Excellent resistance to rapid cold‑hot alternation. Hard to crack under frequent temperature fluctuation, reliable for high‑temperature working stations.
■ Excellent Corrosion & Oxidation Resistance
Chemically inert to acids, alkalis, salt mist and most industrial slurries. Resist high‑temperature oxidation, no rust or surface degradation in humid and corrosive conditions.
■ Precision Machined Mounting Holes & Profiles
Tight‑tolerance processing for embedded cavities, mounting holes, notches and locating surfaces. Ensure perfect matching with pins, shafts and insert parts, good assembly repeatability.
■ Non‑magnetic & Electrical Insulation
Non‑magnetic feature and reliable insulation performance, suitable for semiconductor, electronics and magnetic‑field‑sensitive production lines.

Main Applications:

High-temperature furnace protection tubes, thermocouple insulating sleeves, metallurgical molten metal conveying and shielding tubes, semiconductor thermal processing equipment, new energy high-temperature modules, chemical anti-corrosion piping and industrial high-temperature insulating structural parts.

Main Applications of Ceramic Substrates
Thanks to these desirable properties, ceramic substrates find applications in a variety of industries.

● The Automotive Industry

You can find a broad range of ceramics employed to make electric power steering, integrated starter alternators, diesel and water pump controls, and motor and engine controls for vehicles. These devices could not only reduce fuel consumption but also decrease exhaust pollution.

● The Renewable Energy Field
These substrates are applied to the renewable energy industry to manufacture inverters for photovoltaics solar and concentrators for concentrator photovoltaics.
