B2O3对CaO基渣精炼的助熔作用和脱硫的影响

Fluxing Action and Desulphurizing Effect of B_2O_3 on CaO - Based Refining Slag

B2O3有一定的助熔作用，能降低玻璃高温粘度，但当B2O3/Na2O实际比值大于1时，会出现硼反常现象；

B_2O_3 can assisted the melting and decreased the high temperature viscosity , but when the B_2O_3 / Na_2O was more than 1 , the boron abnormality happened ;

碱金属氧化物、冰晶石、B2O3主要起助熔作用，降低玻璃熔制温度，加速玻璃的澄清和均化，间接防止着色剂硒和硫的挥发。

Introducing of alkali metal oxide , borax , cryolite facilitates melt and accelerates the refining and homogenizing of glass , so they can indirectly prevent the colorant from evaporating .
