  3. Borosilicate glass - Wikipedia

    en.wikipedia.org/wiki/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.

  4. Porous glass - Wikipedia

    en.wikipedia.org/wiki/Porous_glass

    Porous glass is glass that includes pores, usually in the nanometre- or micrometre-range, commonly prepared by one of the following processes: through metastable phase separation in borosilicate glasses (such as in their system SiO 2-B 2 O 3-Na 2 O), followed by liquid extraction of one of the formed phases; [1] [2] through the sol-gel process; or simply by sintering glass powder.

  5. Vycor - Wikipedia

    en.wikipedia.org/wiki/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.

    en.wikipedia.org/wiki/Strength_of_glass

    S-glass has a strength of 700,000 pounds per square inch (4,800 MPa) while E-glass and C-glass have a strength of 500,000 pounds per square inch (3,400 MPa). [ 9 ] Hardness

  7. Crown glass (optics) - Wikipedia

    en.wikipedia.org/wiki/Crown_glass_(optics)

    The borosilicate glass Schott BK7 (glass code 517642) is an extremely common crown glass, used in precision lenses. Borosilicates contain about 10% boric oxide, have good optical and mechanical characteristics, and are resistant to chemical and environmental damage.

  8. Calculation of glass properties - Wikipedia

    en.wikipedia.org/.../Calculation_of_glass_properties

    The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...

  9. Prince Rupert's drop - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_drop

    Prince Rupert's drops have remained a scientific curiosity for nearly 400 years due to two unusual mechanical properties: [4] when the tail is snipped, the drop disintegrates explosively into powder, whereas the bulbous head can withstand compressive forces of up to 664,300 newtons (67,740 kg f).
