VYCOR^® Code 7913

Special Properties

• Low thermal expansion
• High temperature resistance
• High temperature change resistance
• Low specific weight
• Heat resistant 96% silica glass
• Good chemical resistance
• More economical than quartz glass

Typical Applications

• Ultraviolet applications
• Dielectric components
• Quartz Glass / Fused Silica substitution
• Heat shields
• VYCOR windows
• Heat resistant glass components
• VYCOR Substrates and glass wafers

The thermal characteristics of VYCOR^® are compareable to those of quartz glass or fused silica whereas VYCOR is more economical. A good temperature resistance allows the use of VYCOR glass at high continous operating temperatures of up to 900°C. The 96% portion of SiO2 in VYCOR's glass composition results in a low coefficient of thermal expansion and a good thermal shock resistance. VYCOR glass withstands harsh environmental conditions like acids, water, steam, low and high temperatures better than most other glass materials. VYCOR raw material from Corning comes in rolled sheets and is ground and polished to the technical requirements. Not at least the interesting electrical characteristics of VYCOR, a high ultraviolet and visible transmission make VYCOR a good choice for many technical optical applications.
