透明氧化铁颜料生成条件的研究

STUDY ON GROWTH CONDITION OF TRANSPARENT IRON OXIDE PIGMENT

对硫酸亚铁溶液用氢氧化钠和碳酸氢铵为沉定剂生成透明氧化铁颜料的条件进行了初步研究。这些条件包括温度、pH值、空气流量等。并对颜料的制备过程进行了某些改进。

Some growtk conditions of transparent iron oxide pigment in the solution of ferrous sulphate with NaOH and NH_4HCO_3 as precipitant were investigated. The process was studied in terms of temperature, pH, and air flow. The reformations of its preparation process were made.
