Goodfellowhas expanded its range of advanced ceramics with the addition of high thermal conductivity silicon nitride.
该材料的导热率为100 w/mk，是氮化硅的四倍，是下一代功率模块，高频电路和LED安装的首选绝缘底物。
高热电导率氮化硅几乎与碳化硅一样轻，但明显强，高断裂韧性，使其具有抗撞击和冲击的能力。可以将其抛光到RA = 0.02µm的表面粗糙度，并且具有异常耐磨性。
The substrate size offered by Goodfellow is 100mm x 100mm with a thickness of 0.32mm. Different sizes and thicknesses may be available upon request. In addition to high thermal conductivity silicon nitride in sheet form, Goodfellow can supply standard silicon nitride as powder, rods, sheets, spheres, targets and tubes.
