硼 酐(粉状)

Boron Trioxide(Powdery)

分子式:B2O3

分子量:69.62
Molecular Formula: B₂O₃
Molecular Weight: 69.62

本产品无色晶状粉末.熔点为450℃,密度为1.085克/毫升,无味,表面有油腻感。在空气中能强烈地吸水生成硼酸。在高温时可被碱金属或镁、铝还原为单晶体硼.氧化硼可溶于酸、乙醇、热水、微溶于冷水,氧化硼可与若干金属化合成具有特征颜色的硼玻璃,能与碱金属、铜、银、铝 锡、砷的氧化物完全混溶。

Colorless crystal powder. Melting point is450℃, its density is 1.085g/ml, odorless and creamy. If left exposed in the air, it will absorbs water intensively to form Boric Acid. At high temper-ature, it can be reduced into single element Boron by Alkali metal, Magnesium or Aluminum. Boron Tri-oxide can be dissolved in acids, ethanol, hot water and slightly in cold water, it can combine with metals to form boron glasses with specific colors,and it can be dissolved in the alkali and oxidized metals such as copper, silver, aluminum, tin and arsenide.

用作硅酸盐分解时的助熔剂、半导体材料的掺杂剂、焊条中的焊药剂、耐热玻璃器皿和油漆耐火添加剂,在冶金工业上用于合金钢的生产,用作有机合成的催化剂,高温用润滑剂的添加剂以及化学试剂。

Used as fluxing agent for silicate decompos-ing, doping agent of semi-conductor materials,additives for heat resistant glass and fire resistant paint, in the metallurgical industry, it can be used for alloy steel smelting, also it can be used as catalysts for organic synthesis, additive for high temperature lubricant, as well as chemical reagents.
