用途：
1.玻璃与玻璃纤维
　　在制造隔热玻璃棉、纺织玻纤和硼硅玻璃（耐热玻璃、电光源玻璃、玻璃烧器、***/化妆品的包装瓶、中空微珠、光学镜片、密封玻璃）等领域，硼砂作为提供B2O3的原料。当玻璃中的钠硼比例需要控制时，它与硼酸组合作为提供钠离子的原料。
　　玻璃中的B2O3有两种功能：一是助熔剂，二是网络形成体。它控制着玻璃的熔点和***终产品的性能。
　　玻璃棉中的B2O3有助于“纤维化”和提高玻纤的耐久性。硼硅酸盐玻璃中的B2O3可降低玻璃的热膨胀系数（因此可提供对抗热震性），并改善耐化学性。
2.陶瓷和搪瓷釉料
　　硼砂可增加陶瓷（如墙地砖、餐具、陶瓷器皿和搪瓷设备等）的抗压强度、耐磨性和抗化学性。由于B2O3对热膨胀系数的控制使得坯釉适应行提高。同时，B2O3也可降低熔融温度，防止失透。使得产品更光滑更***。
3.洗涤剂和漂白剂
　　硼砂可以用来生产过硼酸钠，过硼酸钠在洗衣粉中起漂白作用。在洗涤过程中可同时起软化水和PH缓冲剂作用，有利于去除油垢，对于液体洗涤剂硼砂是酶稳定剂。
4.清洗剂
　　在许多的清洗剂中，硼砂即起着PH值缓冲剂，以有助于油的乳化。同时还有耐腐蚀作用。当与多元羟基化合物结合时，硼砂可控制粘度。所以它被加入到清洗剂中用来清洗坚硬的表面，如金属、玻璃及卫生间设备。此外它还作为洁手剂、上光剂、石蜡以及工业和民用清洗剂的添加剂。
5.阻燃剂
　　硼酸盐改变了赛璐璐材料在燃烧过程中的氧化反应以形成残余碳。这种残馀的焦炭阻止了燃烧或使分解的产物转而焖烧。硼砂与硼酸组合对阻止赛璐璐类材料燃烧尤其有效。
6.防锈
　　硼砂被加在许多有防锈要求的水溶液中。它保护铁制金属不受氧化。还被用于汽车防冻液、水处理药剂、金属制造等方面。
7.粘结剂
　　硼砂是制造瓦楞纸粘结剂的成份之一，同时也是制造酷蛋白和糊精粘结剂的胶溶剂。硼砂通过交联键羟基极大地改善了湿胶强度。
8.其它应用
　　硼砂作为金属拉丝中润滑剂的载体，在耐火材料中作为稳定剂和骨架形成体，在冶金中作为包裹助熔剂，水泥和混凝土的缓凝剂、水系统中PH值缓冲剂、石蜡的乳化剂。

English: tetraborate decahydrate Sodium
Molecular weight: 381.37
Na2B4O7 10H2O structured: j
Character: it is colorless translucent crystals or white clean powder. Odourless. Taste salty. The relative density were 1.73. Slightly soluble in cold water, slightly soluble in hot water. Soluble in glycerin. Slightly soluble in ethanol and carbon tetrachloride. In alkaline solution. At 60 ℃ lost eight gesso, when ℃ in 320 gesso lose all. In the air can slow weathering. During melting into a colourless glass substance. Can counteract acid. But with alkali a weak acidity is again together. Borax acid-base duality makes it the best slow granule.
USES:
1. Glass and glass fiber
In manufacturing heat insulation glass cotton, textile fiberglass and high-borosilicate glass (heat-resistant glass, electric light source glass, glass burned device, drug/co***etics packaging bottles, hollow beads, optical lens, sealing glass) and other fields, borax B2O3 raw materials as providing. When the glass of sodium boron proportion need to control, it with boracic acid sodium i*** provide combination as a raw material.
B2O3 in glass has two functi***: one is the flux, 2 it is network forming body. It controls glass melting point and the performance of the final product.
The glass wool B2O3 help "fibrosis" and improve the durability of the e. Boron silicate glass B2O3 can reduce glass of thermal expansion coefficient of (and therefore can provide against thermal shock sexual), and improve chemical resistance.
2. Ceramics and enamel as expected
Borax can increase the ceramic (such as tiles, tableware, ceramic vessels and enamel equipment, etc.) and the compressive strength and wear resistance and chemical resistance. Due to thermal expansion coefficient of B2O3 control makes billet glaze. Do improve to Meanwhile, B2O3 also can reduce melting temperature, prevent loss through. Make product more ***ooth more perfect.
3. Detergent and bleach
Borax can be used for production of boric acid sodium, boric acid sodium plays a role in washing powder bleach. In washing process can simultaneously on water and PH slow granule softening effect, helps remove oil dirties, for liquid detergent borax is enzyme stabilizer.
4. Cleaner
In many of the detergent, borax namely plays PH slow granule, to help the emulsifying oil. And corrosion resistant function. When combined with multiple hydroxyl compound, borax can control viscosity. So it was added to the cleaner to cleaning hard surface, such as metal, glass and toilet facilities. In addition, it is also as a clean hand agent, polish, paraffin wax and industrial and civil detergent additives.
5. Flame retardant
Borates changed the life of materials in the combustion process oxidation reaction to form a residual carbon. The remaining coke prevented the product of burning or make braised burn to decompose. Borax and to prevent the life of boric acid combination of materials combustion is especially effective.
6. Antirust
Borax is added to many antirust requirements in aqueous solution. It protects the iron metal from oxidation. Also be used in automobile antifreeze, water disposal reagents, metal manufacturing, etc.
7. Binder
Borax is making one of corrugated binder ingredients, but also make cool protein and dextrin binder rubber solvents. Borax through a cross-link hydroxyl greatly improved the wet adhesive strength.
8. Other applicati***
Borax as the carrier in the metal wiredrawing, lubricants refractory as stabilizers and skeleton in metallurgy, formed body as parcel flux, cement and concrete retarder, water system PH slow granule, paraffin wax emulsifier.
