会社のニュース Shaanxi Kegu Recognized as “Excellent Partner” by NGK Technocera Suzhou Co., Ltd. in 2025

SUZHOU, China — Shaanxi Kegu Advanced Materials Technology Co., Ltd. has been awarded the “Excellent Partner” title for 2025 by NGK Technocera Suzhou Co., Ltd., recognizing its performance in product quality, delivery consistency, and technical collaboration.

The award reflects Kegu’s long-term supply of pressureless sintered silicon carbide (SSiC) components used in high-temperature and corrosion-sensitive industrial applications.

Focus on Material Consistency and High-Temperature Performance

According to disclosed technical specifications, Kegu’s SSiC materials are characterized by:

• Bulk density of ≥ 3.05 g/cm³
• Near-zero open porosity
• Flexural strength of ≥ 380 MPa at room temperature and ≥ 420 MPa at 1300°C
• Thermal conductivity of approximately 116 W/m·K
• Coefficient of thermal expansion of ~4.0 ×10⁻⁶ /K
• Maximum service temperature up to 1650°C in air

These parameters are relevant for applications where dimensional stability and resistance to thermal stress are required.

Applications in Semiconductor and Industrial Systems

SSiC components supplied by Kegu are used in:

• Semiconductor manufacturing equipment
• High-temperature kiln and furnace systems
• Chemical processing environments requiring corrosion resistance
• Precision ceramic fixtures

The combination of high thermal conductivity and low thermal expansion helps mitigate thermal gradients in these systems.

Manufacturing and Supply Chain Capabilities

Kegu’s production process includes pressureless sintering at temperatures exceeding 2100°C, with control over particle size distribution and forming methods such as isostatic pressing.

The company reports machining capabilities including:

• Dimensional tolerance of ±0.02 mm
• Surface roughness up to Ra ≤ 0.8 μm
• Support for complex geometries through CNC and grinding

In addition, its supply system incorporates batch-level consistency control and full traceability from raw materials to finished components.

Industry Context

Pressureless sintered silicon carbide is widely used in industries requiring materials with high thermal stability and chemical resistance. Compared with alternative ceramic materials, SSiC is typically selected for applications involving elevated temperatures and aggressive chemical environments.
