Chemistry Property
1. Antioxidation Property of Elements
Our cutting-edge element begins its robust antioxidation process at 800°C in air, producing a SiO protective film on the surface of the hot zone as temperatures reach an impressive 1000-1300°C ; at 1300°C, cristobalite crystallizes; the protective film reaches optimal thickness at 1500°C , dramatically slowing oxidation to a stable pace. However, if heated beyond the threshold of 1627°C , the protective film will degrade, accelerating oxidation and potentially leading to premature element deterioration.
Though oxidation occurs at a very slow pace during use, it still causes resistance to increase over time due to a phenomenon known as 'ageing.' To combat this, our specialized technology applies a protective film during production, significantly boosting the element's antioxidation properties and extending its service life.
2. The Influence of Alkali and Alkaline Metal Oxideson Elements
Alkali and alkaline metal oxides react with SiC around 1300°C to form silicates, leading to alkali-chemical corrosion, which can impact the element's glow.
3. Effects of Molten Metals on Elements
Certain metals like cobalt, nickel, and chrome can corrode the element in their high-temperature molten states, affecting the element's longevity.
Electric Property
SIC heating elements exhibit a significant specific resistance. When heated in air and reaching a surface temperature of 1050ºC, their resistance rate ranges from 600-1400 mm2/mm (square millimetre). This resistance value fluctuates with temperature. From room temperature to 800ºC , the value is negative; above 800ºC , it follows a positive value nature curve.

Guidelines to Order Your SiC Heating Element
1. Select the configuration you require: Whether it's a Rod, U, W, Single Spiral, or other forms.
2. Specify the Outer Diameter (OD) desired for your application.
3. Determine the Heating Zone Length (HZ) to match your needs.
4. Define the Overall Length (OL), ensuring compatibility with your setup.
5. Indicate the specific Resistance required for optimal performance.
Example Order: Rod configuration, OD of 30mm, HZ of 300mm, OL of 800mm, with a Resistance of 0.4 ohms.
Installation Instructions
1. Ensure the silicon carbide heating element remains impeccably dry throughout both storage and installation, safeguarding its superior performance.
2. Prior to assembly, each element must be separated. The resistance variation among them should not exceed a 10% threshold to maintain optimal functionality.
3. Exercise utmost caution during both usage and maintenance to preserve the longevity and effectiveness of the heating elements.
4. Gradually elevate the voltage when initiating the electric furnace operation. Avoid loading the system to full capacity immediately to prevent damage from excessive current.
5. When replacing a damaged heater, ensure the new heater's resistance aligns with the current resistance levels. If numerous heaters are compromised or show significant resistance increases, a complete replacement is advisable.
