Spectral Transmission of Major Optical Grade Silica Glass Material Silica glass has specific properties which cannot be seen in other materials. For example, rigidity, pulling strength, bending strength and the like rise with a temperature rise, and culminate at from 800 degree C to 1,000 degree C, and suddenly decrease at the temperature exceeding such specified temperatures.
The properties of the non-oxide ceramic silicon nitride (Si3N4) make this CeramTec ceramic the material of choice for extremely demanding appliions: Among other features, Si3N4 ceramics are resistant to impact and strikes thanks to their very high fracture
so-called globar made of silicium carbide with a glowing temperature of 1500K. The beam of infrared light passes a monochromator and splits into two separate beams: one runs through the sample, the other through a reference made of the substance the sample
