Paper Abstract

The constant evolution in the decreasing of the fiber price on the market leads manufacturers to reduce the cost of production. Thus, we propose to enhance the preforms production by shortening the manufacture time. In this way, we have replaced the usual bubbling method by a direct evaporation and regulation of chloride. Such a method allow to increase significantly the SiCl4 gas flow. In the other hand, it is also possible to use the direct evaporation method for other processes such as O.V.D, V.A.D... Nevertheless we may pointed out that the direct evaporation method is cheaper than usual one when the SiCl4 mass-flow is greater than 10
