Kodi ndi chiyaniGalasi la Borosilicate?
Galasi la Borosilicate ndi mtundu wa galasi lomwe lili ndi silica ndi boron trioxide ngati zinthu zazikulu zomwe zimapanga magalasi. Magalasi a Borosilicate amadziwika kuti ali ndi ma coefficients ochepa kwambiri a kutentha (≈3 × 10⁻⁶ K⁻¹ pa 20 °C), zomwe zimapangitsa kuti azilimbana ndi kutentha kwambiri kuposa galasi lina lililonse lodziwika bwino. Galasi lotereli silimakhudzidwa ndi kutentha kwambiri ndipo limatha kupirira kutentha kosiyanasiyana popanda kusweka kwa pafupifupi 165 °C (297 °F). Limagwiritsidwa ntchito kwambiri popanga mabotolo ndi ma flasks komanso magetsi, zamagetsi ndi ziwiya zophikira.
