某些生产镁的企业利用添加氯化钠的光卤石做原料。为此弄清楚随着氯化钠浓度的增加,熔体的电导率可提高多少是非常重要的。往工业沸腾炉生产出的一次脱水光卤石中加NaCl。在四电极石英电解槽中用电压-电流表测定了技术量数,精确度3～4％。这个电解槽的常数值是根据已知的氯化钾溶液电导值求出的,等于325厘米~(-1)。 Some companies that produce magnesium use sodium chloride added carnallite as raw material. To do this it is important to understand how much the conductivity of the melt can be increased as the sodium chloride concentration increases. To industrial boiling furnace to produce a dehydrated carnallite plus NaCl. In the four-electrode quartz cell with a voltage - ammeter measured the technical quantities, accuracy of 3 to 4%. The constant value of this cell is based on the known conductivity of potassium chloride solution and is equal to 325 cm -1.
