White silica—a hard core with a bright surface


Our 'white quartz' is a very special filler that combines the best properties of quartz and cristobalite in the form of a part-cristobalized quartz. In this case a quartz core is enclosed in a cristobalite coating, which gives the white silica the stability of quartz and the high degree of whiteness of cristobalite. In addition, the core surface is slightly cracked. This high-performance filler is an excellent choice, for example, for emulsion-bound plasters, silicate plasters and road marking paint. It is also particularly suitable for 'engineered stone' applications.
