Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.
2009/3/31· 8. The IR generator of claim 1, wherein the material of the electro-thermal body is semiconductor-like self-heating material. 9. The IR generator of claim 8, wherein the electro-thermal body is a silicon carbide resistance. 10. The IR 11.
2012/2/21· Modern white LEDs are based on indium gallium nitride (InGaN), deposited on a transparent substrate such as sapphire or silicon carbide (SiC). The band gap of InGaN can be manipulated by altering the ratio of GaN to InN such that emitted photons are in the 390 to 440 nm part of the spectrum (ultraviolet, violet-blue, and blue).
