Introduction &Application

Zircon powder is ZrSiO4 (for) zirconium silicate minerals, composed of main components of castings have strong ability of quench resistance, good adhering sand.To prevent defects casting surface effect. Casting surface is smooth,

 easy cleaning.

1).Used in investment casting, large castings and alloy steel castings surface sand or coating.2). Used as metallurgy, chemical industry etc of refractories.3). zircon powder in ceramic industry as the main materials, also used to glaze, makes the finest resistance and increase of surface finish
