Nepheline syenite is a naturally occurring rock that consists mainly of the minerals albite, microcline and nepheline. This mineral raw material therefore contains no crystalline quartz; it is inert and is characterized in addition by a high degree of hardness (Mohs hardness 6.5). Furthermore, the high degree of whiteness and the excellent transparency are popular in industrial processing. Our high-grade nepheline syenite has not only proven itself as a high-performance filler in the production of porcelain and ceramics, but is also highly suitable as an anti-blocking additive in plastic film and as a filler for wood varnishes and decorative paints. You can also benefit from our premium product quality!
