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. [citation needed] Vycor can be subject to prolonged usage at 900 °C. [1]
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking ...
The indices of refraction of glass laser hosts may be varied between approximately 1.5 and 2.0, and both the temperature coefficient of n and the strain-optical coefficient may be tailored by altering the chemical composition. Glasses have lower thermal conductivities than the alumina or YAG, however, which imposes limitations on their use in ...
Ultra low expansion glass has an coefficient of thermal expansion of about 10 −8 /K at 5–35 °C. [2] It has a thermal conductivity of 1.31 W/(m·°C), thermal diffusion of 0.0079 cm 2 /s, a mean specific heat of 767 J/(kg·°C), a strain point of 890 °C [1634 °F], and an estimated softening point of 1490 °C [2714 °F], an annealing point ...
Corning was the glass supplier for lightbulbs for General Electric after Edison General Electric merged with Thomson-Houston Electric Company in 1892. [34] It was an early major manufacturer of glass panels and funnels for television tubes, invented and produced Vycor (high temperature glass with
Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion making it more resistant to thermal shock than most other glasses. [10] Quartz glass can withstand very high temperatures and is transparent in certain parts of the electromagnetic spectrum.
