? ? 鋯英砂理論組成為：ZrO2:67.1；SiO2:32.9。純凈的鋯英砂為無色透明的晶體，常因產地不同、含雜質的種類與數量不同而染成黃、橙、紅、褐等色，比重的變化有時與成分和蝕變狀態有關。鋯英石是一種主要由火成巖形成時從巖漿中結晶出來的鋯、硅和氧組成的礦物。鋯英石也產于巖脈和變質巖中。它屬四方晶系，常呈發育良好的錐狀小四方柱體，也成不規則粒狀。性脆，斷口貝殼狀。是優質的耐火材料。多與鈦鐵礦、金紅石、獨居石、磷釔礦等共生于海濱砂中，經水選、電選、磁選等選礦工藝分選后而得到。

Zircon sand theory is composed of: SiO2:32.9; ZrO2:67.1. Pure zircon sand is a colorless and transparent crystal, often due to different producing areas, with different types of impurities and the number of yellow, orange, red, brown and other colors, the proportion of the change and the composition and alteration of the state. Zircon is mainly an igneous rock formed from magma crystallized zirconium, silicon and oxygen composition of minerals. Zircon is also produced in the dikes and metamorphic rocks. It belongs to tetragonal system, which is usually well developed, and it is also irregular and granular. Brittle fracture, fracture shell shape. High quality refractory material. And ilmenite, rutile, monazite, xenotime is born in beach sand, through the water and electricity choose and magnetic beneficiation process.
?
?
Zircon sand is mainly used in refractory raw materials, ceramics, glass, paint, casting industry and other fields.
??Refractory raw materials: for production Brick zircon, zirconium just jade electric melting brick, sintering brick, brick, glass furnace zirconium incompletely play materials, castables.
??Ceramic: chemical stability, is a high-quality, inexpensive opacifying agent, is widely used in the production of all kinds of building ceramics, sanitary ceramics, ceramics for daily use, a ceramic crafts such as, in the production of ceramic glaze, using a range wide, can significantly improve the ceramic body and glaze combination of performance and increase the hardness of the ceramic glaze;
??Glass: the television industrys color picture tube, glass industry, emulsion glass;
??Coatings: good suspension stability, with excellent thixotropy and liquidity, coating, the coating has no brush marks, organic matter content low, small volume, high strength coating, zircon powder on casting a strong chilling ability, good anti sticking sand, can effectively prevent the surface defects of castings, casting surface is bright and clean, easy to clean. Suitable for large and medium sized steel castings, cast iron and non-ferrous alloy castings. Suitable for water glass sand, clay sand and resin sand especially various sand core;
??Casting: good thermal conductivity, small thermal expansion, good thermal shock stability, high degree of fire resistance, zircon sand heat storage coefficient is also larger. Can improve the casting surface quality and size precision of the strong chilling effect on casting and fine metal structure, improve the mechanical properties, zircon sand for the veil of the large cast steel pieces of wall thickness and all kinds of alloy steel castings, as a surface layer material has the role of grain refinement, used as a surface layer material and sanding material is formulated, used for the production of stainless steel investment castings.
?
?
Transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge, to reduce the breakage of packing, the impact of the use.
Storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
