Advantages of silicon carbide heat radiation panels
High-efficiency heat dissipation
In high-temperature processes such as semiconductor LPCVD, photovoltaic cell diffusion, and cover glass hot bending, even minute temperature differences at the heat source can cause problems such as wafer warping and uneven film thickness.
GORGEOUS CERAMICS (GGS Ceramic)’s silicon carbide thermal radiant plates effectively address this issue, rapidly distributing locally concentrated heat across the entire plate with a millisecond-level response.
- Ultra-high thermal conductivity of 160W/(m·K): The product boasts a thermal conductivity of up to 160W/(m·K), eliminating localized hot spots and controlling the surface temperature difference to approximately ±1℃.
- High emissivity and efficient heat transfer: Our product’s infrared emissivity is approximately 0.90, significantly improving thermal radiation efficiency and reducing heating power consumption by 15%–20%.
Fast thermal response
In cyclical thermal equipment requiring frequent heating, holding, and cooling, such as semiconductor rapid heat processing, the inherent thermal inertia of the heat radiant plate is a major bottleneck for improving production efficiency.
GORGEOUS CERAMICS (GGS Ceramic) silicon carbide heat radiant plates possess excellent thermal conductivity and heat diffusion capabilities, enabling rapid heat transfer and diffusion across the entire plate surface, while simultaneously releasing heat quickly during cooling.
Compared to materials with low thermal conductivity, our silicon carbide heat radiant plates reduce heat retention within the plate, allowing equipment to reach target temperatures and respond to temperature changes more quickly.
Maintain stable plate surface geometric accuracy
Heat radiation plates are exposed to high temperatures for extended periods. If warping or deformation occurs, it alters the distance between the plate and the workpiece, causing changes in heat radiation distribution and affecting the stability of the entire temperature field.
GORGEOUS CERAMICS (GGS Ceramic) silicon carbide heat radiation plates are manufactured using a high-temperature sintering process with precise control over the plate structure and sintering shrinkage. Under long-term high-temperature loads of 1200℃-1350℃, the product’s creep rate is close to zero, and its high-temperature bending strength reaches 450MPa, effectively preventing plate dents and warping.
