Vycor is a 96% silica glass, ideal for high temperature applications.
It has similar properties and performance levels to quartz.
Its can be continuously used at 900°c with peaks at 1200°c.
Its extremely low thermal expansion coefficient confers excellent resistance to thermal shock.
For instance, a 3 mm thickness plate heated to 1200°c and dropped in cold water does not break.
Vycor has a very high resistance to acids, water, and steam at low and high temperatures. It is characterized by high electrical resistance and low dielectric losses. It is worked hot, can be machined and polished for use in optics.
Vycor® exists in sheets and tubes.
