Abstract
The present invention relates to a glass including, represented by mole percent based on oxides: from 52% to 80% of SiO2; from 5% to 30% of B2O3; from 2% to 30% of Al2O3; from 0.1% to 11% of P2O5; and from 0.0001% to 5% of Na2O, in which the glass has an average thermal expansion coefficient α at from 50° C. to 350° C. of from 5×10−7/° C. or more and less than 33×10−7/° C.
Claims19
A heat-resistant member, comprising:
- a glass sheet comprising a glass, and
- a ceramic having a thermal conductivity of 25 Wm/K or more and bonded to the glass sheet by fluororesin bonding,
- wherein
- the glass comprises:
- a composition comprising, by mole percent based on oxides,
- 52% to 80% of SiO2,
- 5% to 30% of B2O3,
- 2% to 30% of Al2O3,
- 0.1% to 11% of P2O5, and
- 0.0001% to 5% of Na2O, and
- wherein the glass has an average thermal expansion coefficient α in a range of 5×10−7/° C. to less than 33×10−7/° C. at a temperature in a range of 50° C. to 350° C.
