Sulfur containing silica particle

A product produced by filtering an aqueous-based material from a composition comprising a compound containing the following formula (SiO2)x(OH)yMzSaF in the aqueous-based material:

• wherein M is at least one of the following metal cations:
• boron, magnesium, aluminum, calcium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, zirconium, molybdenum, palladium, silver, cadmium, tin, platinum, gold, and bismuth;
• wherein S is a sulfur-based species selected from at least one of the following:
• sulfide salts, dithiocarbamates, polymer-based dithiocarbamates, and polysulfide salts;
• wherein F optionally exists and said F is at least one of the following:
• a functionalized organosilane, a sulfur-containing organosilane, an amine-containing organosilane, and an alkyl-containing organosilane at a surface area coverage of 0.01-100%;
• wherein the molar ratio of y/x is equal to 0.01-0.5, the molar ratio of x/z is equal to 3-300, and the molar ratio of a/z is 1-5;
• and wherein the compound comprises 3% to 15% by weight in the aqueous-based material.
