    摘要: Bubble-free core glass can be deposited at relatively high rate (e.g., >0.3 gm SiO.sub.2 /minute, preferably 0.6 gm SiO.sub.2 /minute or more) by MCVD if the deposition conditions are appropriately selected. For instance, a relatively high torch traverse speed, a relatively low sintering temperature, and/or relatively low gas flow rates can facilitate high rate deposition of bubble-free glass. By way of example, conditions are disclosed that yielded essentially bubble-free core glass (.DELTA.=0.35%) at a rate of 1 gm SiO.sub.2 /minute.
