高岭土的质量和品位是决定其价格高低的重要因素。1987年法国高岭土(含水12—13％)的市场价格为:陶瓷用高岭土400法郎/吨;造纸填料用高岭土600法郎/吨;纸张涂料用高岭土850—1000法郎/吨;油漆填料用高岭土1500法郎/吨。法国高岭土的产量和消耗量逐年有所增加,1986年高岭土总产量为356045吨,国内消耗总量约484200吨(见表1)。法国高岭土的生产主要集中于5家公司。索卡(Soka)是法国生产高岭土最大的一家公司,年产高岭土120000吨,其中35％左右用于瓷砖及白水泥;45％用于卫生器具;12％用于耐火材料;8％用于玻璃纤维增强和聚合物。斯内迪(Snekdm)公司1987年高岭土产量为
The quality and grade of kaolin are the important factors that determine the price level. The market price of French kaolin (12-13% moisture) in 1987 was: 400 kaolin for ceramic kaolin / tonne; 600 francs for kaolin for papermaking filler; 850-1000 kaolin for paper coating / tonne for kaolin for paint filler /Ton. The production and consumption of French kaolin increased year by year. In 1986, the total output of kaolin was 356,045 tons and the domestic consumption was about 484,200 tons (Table 1). The production of French kaolin is mainly concentrated in five companies. Soka is the largest French company producing kaolin with an annual output of 120,000 tons of kaolin, of which about 35% is for tile and white cement; 45% for sanitary equipment; 12% for refractories; and 8% for glass Fiber Reinforced and Polymers.
