Minspar™ product line

TQC offers the Minspar™ product line in sizes ranging from a 30-mesh sand to a 2.5µm powder for use as functional fillers in a wide variety of industrial applications. Low in iron and high in alumina, Minspar™ provides the desired flux for most ceramic tile, sanitary ware and glass manufacturing.
