Establishment of the feasibility of a process capable of low cost, high volume production of silane, SiH/sub 4/. Low cost silicon solar array project, Task I. Quarterly progress report, October 1, 1976--December 31, 1976
In the study of a process for the low cost, high volume production of silane (SiH/sub 4/) via redistribution of chlorohydrosilanes, the longevity and nature of the amine functional ion exchange resin catalyst was investigated. A modest decline in catalyst activity appears to be the result of loss of amine function during the initiallizing period. Long term activity remains quite high. In preparation for additional studies, deuterium labeled trichlorosilane is being prepared. The nominally 5 kg/day silane-from-dichlorosilane mini-plant has been constructed, leak tested and conditioned for start up. Approval for operation from a Pre-start Up Safety Review Team has been received in conjunction with an approved flameless method for venting silane. Laboratory studies of the hydrogenation of silicon tetrachloride co-product of the silane process are continuing along with the design of a mini-plant scale unit capable of pressurized operation. Preliminary design of a maxi-plant to integrate the entire process is also underway.
