<p>A method of fabricating an evacuated glass panel, in particular when in the form of evacuated glazing, which incorporates a chamber (18) that is defined by two spaced-apart glass sheets (10 and 12) and a fused edge seal (16). The method comprises positioning the glass sheets (10) and (12) in spaced-apart relationship using pillars (14), and locating a getter (20, 21 or 23) within a region (22) of the chamber that is to be formed between the glass sheets. A fusible sealant material (16) is deposited around the edges of the glass sheets (10 and 12) and air is displaced from between the glass sheets by admitting an inert gas to the space between the glass sheets. After admitting the inert gas the sealant material is fused to create the fused edge seal (16) around the glass sheets whilst maintaining the inert gas in the chamber that is formed with fusing of the sealant material. Thereafter, the chamber is evacuated and, depending upon the type of getter (20, 21 or 23) that is employed, the getter is activated either following evacuation of the chamber or during fusing of the edge seal around the glass sheets.</p> |
