Introduction of zircon sand

Zircon sand, zircon) is a kind of zirconium silicate (ZrSiO4) as the main composition of minerals, the theory of composition is: ZrO2:67.1%; SiO2:32.9%. Pure zircon sand is colorless transparent crystal, often producing area different, the amount and type of impurities and dyed yellow, orange, red, brown wait for color, sometimes the proportion changes related to the composition and altered state.

 

Jin Lin zircon sand is a kind of is mainly composed of igneous rocks formed from magma crystallization from a mineral composed of zirconium, silicon and oxygen. Zircon is produced in dike and metamorphic rock. It belongs to tetragonal crystal system, are often well developed the small square cylinder, cone and irregular granular. Crisp, conchoidal fracture. Is of high quality refractory materials. And ilmenite, rutile, monazite, yttrium phosphate ore were in beach sand, such as the water concentration, electric separation, magnetic separation beneficiation process after sorting and etc.

 

Zircon sand purposes

 

1, Zircon sand is mainly used in refractory materials, ceramics, glass, paint, casting industry, etc.

 

Refractory raw materials: used in the production of zircon brick, zirconium just the quality of the jade fused brick, sintered brick, nozzle brick, glass kiln zirconium ramming material, castable.

 

2, Ceramic, stable chemical performance, is a kind of high quality, low price of opacifying agent, widely used in various construction ceramics, sanitary ceramics, ceramics for daily use, such as the level of ceramic arts and crafts production, in the production of ceramic glaze, using range is wide, can significantly improve the ceramic glaze combined with performance, improve the ceramic glaze hardness;

 

3, Glass: TV industry of colour picture tube, emulsifying glass glass industry;

 

4, Paint: good suspension stability, has good thixotropy and liquidity, coating and coating brushless mark, low organic matter content, hair volume small, the coating with high intensity, zircon powder has strong ability of chilling to the casting, the adhering sand resistance is good, which can effectively prevent the casting surface defects, casting surface is smooth, easy to clean. Suitable for large and medium-sized steel and cast iron and nonferrous alloy casting. Apply to the sodium silicate sand, clay sand especially resin sand and so on all kinds of sand mold core.

 

5, Casting: has 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. For the castings have strong chilling effect, refined metal organization, improve the mechanical properties, zircon sand (powder) for large steel thick wall and all kinds of alloy steel castings, as the surface material has the effect of fine grains, commonly used for preparation of surface layer and sanding materials, used in production of stainless steel and so on of investment castings, to improve surface quality and dimension precision of casting.
