In a first step, biogenically concentrated silica is mixed with a liquid polyol to obtain a mixture, and then the mixture is heated. In a second step, a base is added to obtain a reaction mixture. In a third step, the reaction mixture is filtered to remove the carbon enriched RHA or other undissolved biogenic silica and recover the solution of alkoxysilane and alcoholate. In a fourth step, alkoxysilane is purified by filtering, distilling, precipitating or extracting from the original reaction solution to precipitate various forms of silica. In a final step, residual base present in alkoxysilane is neutralized to eliminate the residual alkali metal base.	07-18-2013

20120309999	AMMONIUM FLUORIDE CHEMISTRIES - A method of removing at least a portion of a silicon oxide material is disclosed. The silicon oxide is removed by exposing a semiconductor structure comprising a substrate and the silicon oxide to an ammonium fluoride chemical treatment and a subsequent plasma treatment, both of which may be effected in the same vacuum chamber of a processing apparatus. The ammonium fluoride chemical treatment converts the silicon oxide to a solid reaction product in a self-limiting reaction, the solid reaction product then being volatilized by the plasma treatment. The plasma treatment includes a plasma having an ion bombardment energy of less than or equal to approximately 20 eV. An ammonium fluoride chemical treatment including an alkylated ammonia derivative and hydrogen fluoride is also disclosed.	12-06-2012
