By special glass, we mean various glass products with unique properties that are imperative in many applications. Our high-grade silica sand has also proven its worth and reliability in special glass. Silica glass from pure quartz is of particular significance in this instance, because it makes possible extremely heat-resistant components, tubes and vessels thanks to its low thermal coefficient of expansion and high thermal shock resistance. Borosilicate glass also enjoys similar popularity, for example, in laboratory applications, because it is also chemically inert in relation to most chemicals. Another large area of application for our silica sands in the special glass segment is vitroceramics, without which modern ceramic hobs would be inconceivable.
The silica sand from the Quarzwerke Group has always been highly suitable for high-grade applications. Furthermore, optical glasses and modules for photovoltaic and solar thermal systems become possible in the first place through our first-class silica sand. The stable and high-grade product properties of our silica sands and feldspars are of special importance for these frequently customized solutions. Only in this way can the special glasses of our long-standing customers be developed and marketed sustainably and unrivalled. The high SiO2 proportion of our silica sand is just as decisive as the absence of pigmenting elements. You can also benefit from our high-grade silica sands for your special technical glass.
