Graphite Thermal Field for SiC Crystal Growth Furnace Market Share Driven by High-Purity Materials Demand and Advanced Furnace Technologies | Valuates Reports

Graphite Thermal Field for SiC Crystal Growth Furnace Market
Graphite is commonly used in thermal fields for SiC (Silicon Carbide) crystal growth furnaces. SiC crystal growth relies on a high-temperature process called the physical vapor transport (PVT) method, which necessitates a stable and uniform thermal environment. Graphite components are ideal for creating this thermal field due to their excellent thermal conductivity, high temperature resistance, and chemical inertness.
The global Graphite Thermal Field for SiC Crystal Growth Furnace market was valued at US$ million in 2023 and is anticipated to reach US$ million by 2030, witnessing a CAGR of %during the forecast period 2024-2030.
