Customization & Sizing: Finding Your Perfect Fit

We understand that unique experiments require specific solutions. KINTEK offers a range of SiC heating elements and the expertise to help you select or customize the perfect fit for your high-temperature application.

How to Specify Your SiC Heating Element Model

• OD: Outer diameter
• HZ: Hot zone length
• CZ: Cold zone length
• OL: Overall length

Example: For an SCR type element with OD = 8 mm, HZ = 100 mm, CZ = 130 mm, OL = 230 mm, and Resistance 4.46 ohms, you can specify its model as: 8*100*230 / 4.46 ohms.

Physical Properties

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.
