MSE PRO Silicon Nitride (Si3N4) Ceramic Substrate
Silicon Nitride (Si3N4) Ceramic Substrate is mainly composed of Si3N4, which is in its most stable form. Among all the ceramic materials, Si3N4 is one of the most popular one due to its great overall properties, such as the ability to handle mechanical stress, high resistance to thermal shock, high thermal conductivity and high wear resistance. These properties allow it to withstand high dynamic stress and high temperature conditions. It is widely used as heat dissipation materials for IGBT and SiC MOSFET in in automotive, electronics, aerospace and biomedical industries.
The high thermal conductivity (>80 W/m.K) of our silicon nitride Si3N4 ceramic substrate is comparable to Maruwa's silicon nitride Si3N4 ceramic substrate.
MSE Supplies also supply various Si3N4 ceramic parts. Please contact us for bulk order or customization.
