مطاط سيليكوني
من أهم مميزاته انه يتحمل درجات الحرارة العالية جدا والمنخفضة جدا فهو يتحمل حراره أكثر من 300 درحه مئويه ودرجة حراره منخفضه حتى - 100 درجه مئويه ودذلك له درجة مقاومه عاليه.

The material formed in the Acheson furnace varies in purity, according to its distance from the graphite resistor heat source. Colorless, pale yellow and green crystals have the highest purity and are found closest to the resistor. The color changes to blue and black at greater distance from the resistor, and these darker crystals are less pure. Nitrogen and aluminium are common impurities, and they affect the electrical conductivity of SiC.
