High-Purity SiC Vertical Furnace Tube High-Temperature Resistant
A Silicon Carbide (SiC) Vertical Furnace Tube is a high-performance ceramic structural component manufactured using processes such as reaction sintering or chemical vapor deposition (CVD). It is specifically designed for extreme environments in semiconductor manufacturing, metallurgy, and high-temperature industries. By leveraging the core material properties of silicon carbide—high hardness, high stiffness, low thermal expansion, high thermal conductivity, and excellent chemical stability—it maintains exceptional dimensional stability (with a coefficient of thermal expansion as low as 4.0-5.0×10⁻⁶/K) and structural integrity under conditions exceeding 1700°C, in corrosive atmospheres, and during rapid temperature changes. It provides a reliable material solution for high-temperature processes.

Q1: What is the primary application of a silicon carbide (SiC) vertical furnace tube?
A1: It is primarily used as a high-temperature reactor tube in semiconductor diffusion furnaces, CVD systems, and industrial kilns (e.g., for SiC/GaN epitaxial growth, oxidation, or annealing processes at 1500–1700°C), providing exceptional thermal stability and corrosion resistance in extreme environments.
Q2: Why choose silicon carbide over traditional materials for vertical furnace tubes?
A2: Silicon carbide offers superior high-temperature strength (up to 1700°C), extreme thermal shock resistance (low CTE ~4.5×10⁻⁶/K), and excellent chemical inertness (resisting acids, alkalis, and plasma erosion), ensuring long service life, minimal maintenance, and stable performance in corrosive atmospheres like HCl or metal vapors.
