Title: Silicone Phosphate
Post by: D4rr3n on October 27, 2011, 01:41:30 PM

I was looking to purchase some Silicone Phosphate for an experiment however after searching I cannot find one single supplier or any info on it. Have I the correct name i.e. a compound which contains Si, P & O or does it not exist?

The second question I have is if I cannot purchase it then how can I make it, would a mixture of phosphorous and silica burned in air produce this?

I'm not sure you have the correct name for the substance you want.  Silicone is a common name for a variety of silicon containing carbon polymers.  You won't get that by simply burning elemental silicon and phosphorous together.  You name may be jargon for a particular field of study.  Maybe if you're more specific about your experiment and the source you're using for the experiment, it would be clearer.

I want to produce an amorphous mass of aluminium oxide plus silicon phosphide.

I believe if I heat aluminium powder with silicon phosphate I should end up with the desired material. The heat generated should help fuse the compounds togeather.

I know not how one could make silicon phosphate, but one possible route to silicon sulfate that would not require high temperatures would be to react silicon tetrabromide with sulfur trioxide.

SiBr4 + (4)SO3 --> Si(SO4)2 + (2)SO2 + (2)Br2

Making SiBr4 does not necessarily require elemental silicon to begin with. See the other thread in this forum: http://www.chemicalforums.com/index.php?topic=54206.0
