| 1. Silicon carbide rod Description |
Silicon carbide rod is one type of ceramic heating element, which uses six-party high purity green SiC powder as the main raw material. Silicon is recrystallized under 2200C high temperature to form finished materials. The using temperature up to 1450C under oxidation atmosphere, and constant working life up to 2000 hours. It is widely used in various high-temperature electric furnaces and other electric heating devices

Ceramic Fiber Blanket is a lightweight insulating product. It has low thermal mass which means that it does not retain heat, low thermal conductivity, and is an extremely effective insulation material. Its high thermal shock resistance makes it suitable for applications where traditional refractories cannot be used.
