CaC 2 + 2H 2 O → C 2 H 2 + Ca(OH) 2 Calcium carbide also reacts with nitrogen gas at elevated temperatures (1,000–1,200 °C [1,800–2,200 °F]) to form calcium cyanamide, CaCN 2. CaC 2 + N 2 → CaCN 2 + C This is an important industrial reaction because CaCN 2 finds extensive use as a fertilizer owing to its reaction with water to produce
The Correct Material for Infrared (IR) Appliions
The index of refraction ranges from approximately 1.45 - 2 for visible materials and 1.38 - 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffraction-limited performance can be achieved with fewer lens elements – reducing overall

Silicon on Insulator - an overview | ScienceDirect Topics
Silicon-on-insulator (SOI) is a semiconductor structure consisting of a layer of single crystalline silicon separated from the bulk substrate by a thin layer of insulator. In SOI wafers the insulator is almost invariably a thermal silicon oxide (SiO 2) layer, and the substrate is a silicon wafer. Depending on the type of appliion, the

Band Theory of Electrical Conductivity | Boundless Chemistry
In the case of silicon, a trivalent atom is substituted into the crystal lattice. The result is that one electron is missing from one of the four covalent bonds normally part of the silicon lattice. Therefore the dopant atom can accept an electron from a neighboring atom’s covalent bond to complete the fourth bond.
