The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300°C is 3.3 x 10-6/°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass. Specific heat Specific heat between 25°C and 300°C is average to be 0.233Kcal/Kg, °C
Because borosilicate glass doesn’t expand like ordinary glass, there is a smoother transition between temperatures as well as the ability to withstand different temperatures at the same time. Borosilicate glass has an extremely low coefficient of linear expansion (3.3 x 10 –6 K –1 ) as a result of its low thermal expansion.

Borosilicate - A type of glass with main glass-forming constituents silica and boron oxide. Well know for having very low coefficient of thermal expansion (~5 × 10-6 /°C at 20°C). However, there are many different borosilicate glasses made with various expansion coefficients (e.g. Pyrex and Borofloat are 32.5 while 7059 is 49).
This graduated cup is made of high borosilicate glass and can withstand an instantaneous temperature difference of 200 degrees.It can also be microwaved or refrigerated.

to the different way in which the boric oxide is incorpo rated into the structural network – have only low chemical resistance (B 2 O 3 content over 15 %). Hence we differentiate between the following subtypes. Non-alkaline earth borosilicate glass (borosilicate glass 3.3) The B 2 O 3 content for borosilicate glass is typically 12–13 %
Borosilicate Glass is well-known for its durability, low coefficient of expansion, low density, high softening point, high resistance to acids and thermal shock, compared to other glass formulations. The chemical composition consists primarily of silicon oxide (SiO 2 ) and boron oxide (B 2 O 3 ).

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.

The glass is heat-resistant and can permanently operate at temperatures up to 450 °C. In the short term (< 10 h) it even withstands temperatures of up to 500 °C. BOROFLOAT ® glass has a small coefficient of thermal expansion close to that of silicon, making glass-wafers of SCHOTT's borosilicate glass an ideal solution for anodic bonding
