High Purity Silicon Carbide SiC Powder

Silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, with salt as an additive, and is smelted at high temperature in a resistance furnace. The smelted crystal has high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is Higher than corundum.

Compared with black silicon carbide powder, green silicon carbide has advantages in high temperature, electrical insulation and chemical stability.

Silicon carbide has high hardness, high thermal conductivity, good chemical stability and electrical insulation properties, making it widely used in many fields such as abrasives, ceramics, electronic devices, and high-temperature applications.

Customer: Premium Automotive Components GmbH (Germany)
Application: High-performance converter housings for electric vehicles
Product: Silicon Carbide (SiSiC)

The Challenge
A leading German automotive supplier faced critical design limitations with conventional materials for next-generation electric vehicle power converters. The housings required exceptional thermal conductivity to manage heat from SiC semiconductors, while demanding complex internal geometries for cooling channels that could not be achieved through traditional ceramic forming methods. Weight reduction was equally critical, as every kilogram saved translates directly to extended EV range.

The Solution
Working closely with Kyocera Fineceramics Europe GmbH, the customer adopted additively manufactured silicon carbide components using the binder jetting process . The SiSiC (silicon-infiltrated silicon carbide) material provided exceptional mechanical strength of over 400 MPa and thermal conductivity exceeding 170 W/m·K. The 3D printing process enabled topology-optimized designs that reduced component weight by 25% compared to conventionally manufactured parts .

The Result
The collaboration delivered transformative results. The complex internal cooling channels reduced operating temperatures by 18°C, extending semiconductor lifetime. The weight savings contributed directly to improved vehicle efficiency. As Dr. Carsten Rußner, President of KYOCERA Fineceramics Europe GmbH, noted: "Additive manufacturing enables us to react flexibly to dynamic market requirements. We see great added value for our customers, particularly when it comes to large and complex components" .

The component achieved series production status within 14 months-half the typical development cycle-demonstrating how silicon carbide combined with advanced manufacturing enables automotive innovation.
