<p>: 10 : A method of making an arc tube for a discharge is disclosed together with sealing compositions used in the method. The method consists of assembling together an incompletely fired or green state end closure member (complete with electrode etc.) and an arc tube also in the incompletely fired or green state. Applying a sealing composition selected from the disclosed range and firing this assembly so that the end closure member forms a hermetic seal with the arc tube. Separate steps for producing a completely fired end closure and arc tube and the subsequent step of sealing these two items together is thus avoided. A ternary phase diagram defining preferred compositions is disclosed.</p> |
