Product Overview
Silicon Carbide (SiC) Heating Elements are advanced, non-metallic electric heaters renowned for their exceptional performance in high-temperature environments. Manufactured primarily from high-purity Silicon Carbide, these heater rods offer a unique combination of low thermal expansion, minimal deformation, and outstanding chemical stability. This translates to reliable heat, extended service life, and low maintenance in demanding applications. They operate effectively in air atmospheres from 600°C to 1600°C without the need for a protective gas, making them a versatile and cost-efficient heating solution.
Ideal for a wide range of industrial and scientific processes, they are extensively used in sectors such as metallurgy, ceramics, glass manufacturing, machinery, analytical testing, semiconductor processing, and R&D laboratories.
