NO...

It a very dangerous product...

(From Wikipedia)

Silane can be produced by several routes.[6] Typically, it arises from the reaction of hydrogen chloride with magnesium silicide:

It is also prepared from metallurgical grade silicon in a two-step process. First, silicon is treated with hydrogen chloride at about 300 °C to produce trichlorosilane, HSiCl3, along with hydrogen gas, according to the chemical equation:

The trichlorosilane is then converted to a mixture of silane and silicon tetrachloride. This redistribution reaction requires a catalyst:

All polysilicon plants using the Siemens process make Silane Gas as part of the process... and it is a very nasty and toxic material...

Explosive Silicon Gas Casts Shadow on Solar Power Industry

Silane gas has killed and injured workers at cell-making plants. Can the photovoltaic industry live without it?

In 2007, outside Bangalore, India, an explosion decapitated an industrial worker, hurling his body through a brick wall. In 2005 a routine procedure at a manufacturing plant in Taiwan caused a spontaneous explosion that killed a worker and ignited a blaze that ripped through the factory, shutting down production for three months. Both incidents shared a common cause—silane, a gas made up of silicon and hydrogen that explodes on contact with air. And both incidents occurred in the same industry—solar power.

Among other environmental black marks, the process of manufacturing photovoltaic (PV) cells from silicon relies on this dangerous pyrophoric gas. As the industry gears up to meet growing demand—6.4 gigawatts of new photovoltaic installations were built worldwide in 2009 according to the European Photovoltaic Industry Association, the bulk of it silicon solar cells—what are the human health and environmental concerns related to solar power?

Of course, silane is hardly the only environmental hazard involved in solar cell production. Others include: toxic by-products from polysilicon manufacture dumped indiscriminately in China; air pollution spewed from coal-fired power plants that provide the electricity needed to produce photovoltaics; and recovering cadmium, a known human carcinogen that is a primary ingredient in some thin-film solar cells, from mining slimes. Still, only silane (SiH4) has been linked directly to any deaths as a result of the solar industry.

Yes, I did mention Silane Gas, because that is the raw material used by Amprius to make there Si nanowires...

But this is not one of the niche markets I am looking for, I am looking to replace it...

Hope this helps.
