Since Corning stopped manufacturing Pyrex, a company call Schott has been making an equivelant called BOROFLOAT® 33 Glass. Just like quartz it is highly resistant to chemicals, has a low thermal expansion, high thermal resistance and excellent transmission properties.
The float process provides BOROFLOAT® 33 with a parallel and fire polished surface on both sides and outstanding optical qualities.
Due to its low alkali content, BOROFLOAT® 33 acts as a high-power insulator. BOROFLOAT® 33 is therefore a suitable material for applications where good non-conductive properties at temperatures (up to 450 °C) are called for.
The special structure of borosilicate glass BOROFLOAT® 33 gives it a neutron absorbing effect. Principal Uses
