As a manufacturer of soda ash, Solvay is an acknowledged partner of the glass industry. It is less well known that a whole range of inorganic fluorine compounds plays an important role both in the manufacture of glass and in its processing.
In the manufacture of opaque glass, also known as milk or cloud glass, the cloudiness is achieved by the addition of inorganic fluorides. These are added to the glass melt as so-called “white opacifier”.
In small amounts, fluorides act as fluxes, and only the addition of larger quantities brings about the clouding effect. This clouding effect is caused mainly by the precipitation of small crystals of calcium and sodium fluoride. A typical fluoro- opaque glass will have a fluoride content of approx. 3.5 – 4.0 %.
Hydrofluoric acid is the primary product of the fluorochemical industry, and is the most produced of all inorganic fluoro compounds. It also enjoys a prominent status in the surface treatment of metals .
The requirements for innovative braking systems that can be used worldwide are extremely high. With regard to the braking process they include:
Aspects relevant to the environment will become even more important in the future. At the same time it will be necessary to meet the increasingly stringent specifications of the automobile industry and other sectors with regard to standardization and cost minimization.
Synthetic calcium fluoride from Solvay fulfils these requirements and has proved to be outstandingly good in high performance brakes.
