Chemical Properties
Silicon carbide heating elements exhibit good chemical stability and strong acid resistance. However, at high temperatures, alkaline substances can cause erosion.
Long-term use of silicon carbide elements above 1000°C can lead to reactions with oxygen and water vapor:
① SiC + 2O₂ → SiO₂ + CO₂
② SiC + 4H₂O → SiO₂ + 4H₂ + CO₂
Consequently, the SiO₂ content in the element gradually increases, and its resistance slowly rises, leading to aging. Excessive water vapor can accelerate SiC oxidation. The H₂ generated from reaction ② can combine with O₂ in the air, reforming H₂O and creating a detrimental cycle that reduces component life. Hydrogen (H₂) can also reduce the mechanical strength of components. Nitrogen (N₂) below 1200°C can prevent SiC oxidation; above 1350°C, it can react with SiC, causing decomposition. Chlorine (Cl₂) can completely decompose SiC.
