Vycor® has similar properties and performance levels
Vycor's® properties at high temperatures mean it can be used continuously
at 900°C with peaks at 1200°C.
low expansion coefficient confers excellent resistance to thermal shock.
Example: a 3 mm thickness plate heated to 1200°C and dropped in
cold water does not break!
a very high resistance to acids, water and steam at low and high temperatures.
Vycor® is characterized by high electrical resistance and low dielectric
losses. It is worked hot, can be machined and polished for uses in optics.
Vycor® exists in sheets and tubes.
VYCOR brand glass is a 96% silica and
4% Boric anhydride glass.
Vycor® 7913 is designed for use in all products that
must withstand very high temperatures or thermal shock. It may be used
at much higher temperatures than 7740 Borosilicate glass and will withstand
considerably more thermal shock :
· Modulus of elasticity : 6.500 kg/mm² environ
· Compression breaking load: 3.000 kg/cm² environ
· Softening point: 1500 °C
· Annealing point: 910 °C
· Strain point: 820 °C
· Maximum operating temperature: 900 °C
· Density (g/cm3) : 2.18
· Coefficient of linear
(°C 10-7) : 8
· Refractive index : 1,458
Vycor products can be used continuously
at 900°C, and intermittently to 1200°C.
