He aha teKarahe Borosilicate?
Ko te karaehe borosilicate he momo karaehe me te silica me te boron trioxide ko nga mea nui hei hanga karaihe. Ko nga mohiti borosilicate e mohiotia ana mo te iti rawa o te whakareatanga o te roha waiariki (≈3 × 10⁻⁶ K⁻¹ i te 20 °C), ka kaha ake te atete ki te wiariki i era atu karaihe noa. He iti ake te taumahatanga o te waiariki pera ka taea te tu atu i nga rereketanga o te pāmahana me te kore e pakaru i te 165 °C (297 °F). Ka whakamahia nuitia mo te hanga i nga ipu reagent me nga pounamu tae atu ki te rama, te hikohiko me te tunu kai.
