Stöber process Wikipedia
The Stöber process is a solgel approach to preparing monodisperse (uniform) spherical silica (SiO 2) materials that was developed by a team led by Werner Stöber and reported in 1968. The process, an evolution and extension of research described in Gerhard Kolbe''s 1956 dissertation, was an innovative discovery that still has wide applications more than 50 years later.

The Bayer process is the principal industrial means of refining bauxite to produce alumina and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
