锆英砂简介

锆英石是一种主要由火成岩形成时从岩浆中结晶出来的锆、硅和氧组成的矿物。锆英石也产于岩脉和变质岩中。它属四方晶系，常呈发育良好的锥状小四方柱体，也成不规则粒状。性脆，断口贝壳状。是优质的耐火材料。多与钛铁矿、金红石、独居石、磷钇矿等共生于海滨砂中，经水选、电选、磁选等选矿工艺分选后而得到。锆英石砂具有较低的热膨胀性、较高的导热性，而且较其他普通耐熔材料有较强的化学稳定性，因此优质锆英石和其他各种粘合剂一起有良好的粘结性而用于铸造业。锆英砂（锆英石）用于耐火材料（称锆质耐火材料，如锆刚玉砖，锆质耐火纤维），铸造行业铸型用砂（精密铸件型砂），精密搪瓷器具，此外也用于玻璃、金属（海绵锆）以及锆化合物（二氧化锆、氯氧化锆、锆酸钠、、锆等）的生产中。

锆英砂特点

1、热膨胀系数小，性能可与锆英砂媲美，用其配制型砂，铸件不会产生膨胀缺陷;

2、砂粒为球形，流动性好，易舂实，且透气性好;

3、表面光滑，结构致密，使得粘结剂能均匀覆盖;

4、宝珠砂属中性材料，酸、碱粘结剂均可使用;

5、回用再生性能好，性价比高;

6、耐火度高，易溃散;

7、热导率大，稳定性好，不龟裂;

锆英砂用途

锆英砂（锆英石）用于耐火材料（称锆质耐火材料，如锆刚玉砖，锆质耐火纤维），铸造行业铸型用砂（精密铸件型砂），精密搪瓷器具，此外也用于玻璃、金属（海绵锆）以及锆化合物（二氧化锆、氯氧化锆、锆酸钠、、锆等）的生产中。可制作玻璃窑的锆英石砖，盛钢桶用锆英石砖、捣打料和浇注料；添加到其它材料中可改善其性能，如合成堇青石中添加锆英砂，可拓宽堇青石的烧结范围，而又不影响其热震稳定性；在高铝砖中添加锆英砂，制造抗剥落高铝砖，热震稳定性大大提高；还可用于提取ZrO2。锆英砂可做铸造用优质原砂，锆英砂粉是铸造用涂料主要成分。

zircon sand introduction

Zircon 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 with low thermal expansion, high thermal conductivity, and the other common refractory material has strong chemical stability, so the high quality zircon and other various adhesives with good bonding and used in foundry industry.Zircon sand, zircon) used for refractory material (called zircon refractory materials, such as zirconium corundum brick, zircon refractory fiber), the mould with sand in foundry industry, precision casting sand), precision enamelware, also used in glass, metal (zirconium sponge and zirconium compound (zirconium dioxide, zirconium oxychloride and zirconium sodium, potassium fluoride zirconate, zirconium sulfate, etc.) of production.
zircon sand characteristics
1, small thermal expansion coefficient, performance can be comparable to the zircon sand, with the mixed sand, casting defects will not produce inflation;
2, sand is spherical, good liquidity, easy mixture is real, and the permeability is good;
3, the surface is smooth, dense structure, and makes the binder can uniformly covered;
4, treasure sand is a neutral materials, acid, alkali binder can be used;
5 and the regeneration performance is good, cost-effective;
6, high refractoriness, easy to pieces;
7, large thermal conductivity, good stability, no crack;

zircon sand use

Zircon sand, zircon) used for refractory material (called zircon refractory materials, such as zirconium corundum brick, zircon refractory fiber), the mould with sand in foundry industry, precision casting sand), precision enamelware, also used in glass, metal (zirconium sponge and zirconium compound (zirconium dioxide, zirconium oxychloride and zirconium sodium, potassium fluoride zirconate, zirconium sulfate, etc.) of production.To make glass kiln zircon brick, ladle with zircon brick, ramming material and castable;Added to the other materials can improve its performance, such as synthetic cordierite add zircon sand, can broaden the range of sintered cordierite, without affecting the thermal shock resistance;Zircon sand is added in the high alumina brick, making spalling high alumina brick, thermal shock stability is greatly improved;Can also be used for extraction of ZrO2.Zircon sand casting with high quality can do the original sand, zircon sand powder main composition is foundry coatings.
