Abstract:
1. A method for preventing solids formation in an organosilicon material employed in a chemical vapor deposition process, the method comprising the steps of: providing an organosilicon composition comprising: at least one organosilicon selected from the group consisting of: an alkoxysilane and a carboxysilane; a first concentration of dissolved residual chloride; and a first concentration of dissolved residual chloride scavenger, wherein the organosilicon composition has a first K wherein the first concentration of dissolved residual chloride is less than the square root of the first Ksp(os) when X is 1, less than cubed root of the first Ksp(os) when X is 2, less than the fourth root of the first Ksp(os) when X is 3, or less than the fifth root of the first Ksp(os) when X is 4, and the first concentration of the dissolved residual chloride scavenger is less than the square root of the first Ksp(os) when X is 1, less than cubed root of the first Ksp(os) when X is 2, less than the fourth root of the first Ksp(os) when X is 3, or less than the fifth root of the first Ksp(os) when X is 4; and providing a second organosilicon comprising at least one organosilicon selected from the group consisting of: an alkoxysilane and carboxysilane, a second concentration of dissolved residual chloride, and a second concentration of dissolved residual chloride scavenger, wherein the second organosilicon has a second Ksp(os) defined as the product of [the second concentration of the dissolved residual chloride in parts per million by weight]X, wherein X is 1, 2, 3, or 4, and [the second concentration of the dissolved residual chloride scavenger in parts per million by weight] and wherein each of the second concentration of dissolved residual chloride and the second concentration of the dissolved residual chloride scavenger is less than the square root of the first Ksp(os) when X is 1, less than cubed root of the first Ksp(os) when X is 2, less than the fourth root of the first Ksp(os) when X is 3, or less than the fifth root of the first Ksp(os) when X is 4.
