Application of Zircon sand
Zircon sand is mainly used in refractory materials, ceramics, glass, paint, casting industry, etc.
1) refractory materials:used in the production of zircon.
2) ceramics: widely used in various construction ceramics, sanitary ceramics, daily-use ceramics, ceramic arts and crafts production, such as in the production of ceramic glaze, using range is wide.
3) glass: TV industry of colour picture tube, emulsifying glass glass industry;
4) coating: Apply to the sodium silicate sand, clay sand especially resin sand and so on all kinds of sand mold core.
5) casting:with good thermal conductivity, low thermal expansion and good thermal shock resistance and high refractoriness, the characteristics of the heat storage coefficient of zircon sand is bigger also.
Package: 25 kg / bag or according to Customer requirements.
