高岭土应用在生产纸张、陶器、耐火材料、橡胶、颜料、医药等方面。E.Middleton于1936年首先注意到高岭土生产所产生的危险性。其后K.Lynch与Melver在从事高岭土生产十年以上的工人中发现了一些尘肺病例。目前一种看法是本病肺内粉尘致病过程并非此矿物本身引起,而是矿物中所含的二氧化硅所造成。另一些作者认为作吸入纯高岭土可 Kaolin used in the production of paper, pottery, refractory materials, rubber, pigments, pharmaceuticals and so on. E.Middleton first noted in 1936 the risk of kaolin production. Later, K. Lynch and Melver found some cases of pneumoconiosis among workers who engaged in kaolin production for more than a decade. The current view is that the pathogenic process of dust in the lungs caused by this mineral itself is not caused by the minerals contained in the silica caused. Other authors believe that inhalation of pure kaolin can be
