Vycor

Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes. Vycor can be subject to prolonged usage at 900 °C.[1]

Vycor products are made by a multi-step process. First, a relatively soft alkali-borosilicate

Vycor has an extremely low coefficient of thermal expansion, just one quarter that of Pyrex.[2] This property makes the material suitable for use in applications that demand very high dimensional stability, such as metrology instruments, and for products that need to withstand high thermal-shock loads. Vycor also has ultraviolet transmission to about 250 nm[3] and is used in some germicidal lamps. Based on a reference thickness of 1mm, Vycor glass has an approximately 90% transmission spectra from ~300 nm to 3100 nm.[4]

Vycor can also be used for removal of 231Pa and 233Pa in fuel recycling.[5]
