Micro Titanium Dioxide, often abbreviated as micro TiO2, is a highly versatile and widely used compound in various industries due to its exceptional properties. This minute form of titanium dioxide, with particle sizes typically ranging from 0.1 to 1 micron, offers unique benefits that distinguish it from its macro counterparts. It finds applications in sectors such as cosmetics, paints and coatings, pharmaceuticals, and even advanced materials like solar cells and nanotechnology.

As early as sixty years ago, zinc sulphide was first thought of as a pigment for coloring India rubber and a patent for the process of its manufacture was issued in England. But it was not until twenty years later that zinc sulphide and its manufacture was seriously considered as a pigment for paint, and in 1874 a patent was issued for a process of manufacturing a white pigment, composed of zinc sulphide and barium sulphate, known as Charlton white, also as Orr's white enamel. This was followed in 1876 by a patent issued to a manufacturer named Griffith and the product, which was similar in character to Charlton white, was known as Griffith's patent zinc white. In 1879 another patent for a more novel process was obtained by Griffith & Cawley, the product made under this process proving the best of the series placed upon the market up to that date. After that time many new processes were patented, all, however, tending to the same object, that of producing a white pigment, composed of zinc sulphide and barium carbonate, the results, however, in many cases ending with failure.
