鋯英砂產品介紹說明

? ?? ? 鋯英砂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。鋯英砂也產于巖脈和變質巖中。鋯英砂屬四方晶系，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。鋯英砂多與鈦鐵礦、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 is a mineral consisting mainly of zirconium, silicon and oxygen, which crystallizes from the magma during the formation of igneous rocks. Zircon sand is also found in dike and metamorphic rocks. Zirconium quartz sand belongs to tetrahedral crystal system. It is usually a well-developed cone-shaped small tetrahedron. Zirconium quartz sand is mainly produced in coastal sand with ilmenite, rutile, monolith and yttrium phosphate ore.

◆ 鋯英砂熱膨脹系數小，性能可與寶珠砂媲美，用其配制型砂，鑄件不會產生膨脹缺陷。?

Zircon sand has low thermal expansion coefficient, and its performance is comparable to that of baozhu sand.

?

◆ 鋯英砂表面光滑，結構致密，使得粘結劑能均勻覆蓋。

The surface of zircon sand is smooth and compact, so that the adhesive can be uniformly covered.

?

◆ 鋯英砂耐火度高，易潰散。

Zircon sand has high refractoriness and is easy to break out.

?

◆ 鋯英砂熱導率大，穩定性好，不龜裂。Zircon sand has high thermal conductivity, good stability and no cracking.
