This is a silicon carbide rod (5mm diameter, 50mm long) which is electrically heated to about 1500 K. Water cooling of the electrical contacts is needed to prevent arcing. The spectral output is comparable with the Nernst glower, execept at short wavelengths (less than 5 m) where it''s output becomes larger.

Plain bearings are subject to severe wear when employed in mag-drive or canned motor pumps. The advantage of these pump types is the fact that their design prevents leakage of the fluid pumped, making them extremely environmentally friendly. Up until now, bearing components made of silicon carbide have been used; such ceramic bearings are a good choice since they are highly resistant to

The silicon carbide rod used as the heating element of the globar rod is of length 20-50 mm and width 5-10 mm. It is in the form of a U shaped rod, where the heating element is heated by an
The 6575 is a 22 watt infrared (IR) emitter for use with Oriel''s Q Series and Research Series lamp housings. The spectral irradiance is very similar to a 1273K Blackbody or a Nernst element. Its shape and mounting position allow the emitter to line up well with a
The Nernst lamp was an early form of incandescent lamp.Nernst lamps did not use a glowing tungsten filament. Instead, they used a ceramic rod that was heated to incandescence.Because the rod (unlike tungsten wire) would not further oxidize when exposed to air, there was no need to enclose it within a vacuum or noble gas environment; the burners in Nernst lamps could operate exposed to the air
For the mid-IR region, 2−25 μm (5000–400 cm −1), the most common source is a silicon carbide element heated to about 1200 K (). The output is similar to a blackbody. Shorter wavelengths of the near-IR, 1−2.5 μm (10000–4000 cm −1 ), require a higher temperature source, typically a tungsten-halogen lamp.
Silicon windows have good transmission in the range from 1.2 to 7.0 µm, with little or no distortion of the transmitted signal. Silicon has an advantage over other IR materials due to its low density (about half that of Zinc Selenide or Germanium), making it ideal for

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.
