In view of the potential use of silicon carbide (SiC) in the nuclear industry, it is of major interest to understand point defect formation in this material. This work is a contribution to the determination of the silicon threshold displacement energy in the cubic polytype of SiC using electron irradiations with increasing energies from 275 to 680 keV.
The perfect sphere that will be used to redefine the kilogram in terms of the Planck constant in 2018 has been shown to consist of the purest silicon ever made. The kilogram is the only unit still based on a physical object. The ‘big k’ is a platinum–iridium cylinder
Silicon carbide can operate as a semiconductor in conditions under which silicon cannot adequately perform, such as at temperatures above 400 C. [1]. Silicon carbide gas sensors have been in development for a nuer of years using a range of device

Silicon - Thermal Expansion Coefficient. Linear thermal expansion coefficient of Silicon is 2.6 µm/(m·K). Thermal expansion is generally the tendency of matter to change its dimensions in response to a change in temperature. Beryllium is a chemical element with atomic nuer 4 which means there are 4 protons and 4 electrons in the atomic structure.

Silicon is found in nature in the form of silicon dioxide (like some types of sand and many rocks). The extraction of silicon from silicon dioxide is extremely energy intensive; it requires 1000-1500 megajoules of primary energy per kilogram to process high-grade silicon for computer chips or solar panels.
