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).

Non-alkaline earth borosilicate glass (borosilicate glass 3.3) The B 2 O 3 content for borosilicate glass is typically 12–13 % and the SiO 2 content over 80 %. High chemical durability and low thermal expansion (3.3 x 10–6/K) – the lowest of all commercial glasses for largescale technical applications – make this a multitalented glass

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.
The dielectric material compositions are 55 wt.% Al 2 O 3 and 45 wt.% lead borosilicate glass for G-C(I), 45 wt.% cordierite (2MgO · 2Al 2 O 3 · 5SiO 2) and 55 wt.% borosilicate glass for G-C(II), 35 wt.% SiO 2, and 65 wt.% borosilicate glass for G-C(III). The optimum sintering temperature for these materials is about 900 °C in air.
