ABSTRACT:
A composite capillary tube structure made of a plurality of glass layers and methods for making same. This composite includes inner and outer layers of fused silica glass separated by an intermediate layer of a glass material having a higher coefficient of thermal expansion than the fused silica glass. The glass material of the intermediate layer also has a glass transition temperature on the same order as that of fused silica, so that the fused silica layers are maintained under compressive forces over a temperature range of up to about 400.degree. C. Preferably, the intermediate layer is a borosilicate or aluminosilicate glass.
