  • Dielectric Properties of High-Silica Sand at 2.45 GHz

    An objective of this work is determining electrical properties of high-silica sand used as the base of moulding and core sands containing inorganic binders. The scope of the work includes the commercially available types of high-silica sands having diverse grain size Silica sand is used in paints and coatings to improve the overall look and durability of the paint. Silica fillers improve paint’s tint reduction and dirt resistance, and because of silica sand’s oil-absorption properties it makes a durable coating that’s rich in pigment and resistant to wear and tear.
