Borosilicate glass Wikipedia

+

Borosilicate glass is a type of glass with silica and boron trioxide as the main glassforming 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. Such glass is subjected to less thermal stress and can withstand temperature differentials ...

We report on the influence of oxygen impurities on the gas sensing properties of gallium nitride (GaN) chemiresistors. As shown by XRD, elemental analysis, and TEM characterization, surface oxidation of GaN—for example, upon contact to ambient air atmosphere—creates an oxidative amorphous layer which provides the sites for the sensing toward CO.
