The durability of an alkali‐resistant glass containing ZrO 2 in NaOH solution was studied by scanning electron microscopy. Insoluble Zrrich reaction‐product layers ∼1 to 3 μm thick were observed on the surface of glass which had been soaked for 25 d in 2N NaOH at 95°C. In some cases the layer seems to be an adherent film, but in others it adheres loosely to the glass surface and does not seem to effectively block alkali attack .
