高硅型高可塑性粘土是一种含硅量高、可塑性又很强的粘土,根据其矿物组成又称为高岭石—伊利石—蒙脱石混型粘土。粘土层赋存于侏罗系下一中统煤系地层中,为灰及灰白色砂质泥岩。原矿呈致密块状,易风化。矿体含较多的游离石英。有害组分为铁质。由于粘土矿物中除离岭石外含有多量的蒙脱石,致使粘土矿石具有较强的粘着感,较好的可塑性和较高的结合力,而被电瓷行业所利用,具有较高的工业价值,为研制大型电瓷产品开辟了一个新的国内少有的矿物原料品种。并认为在建筑、卫生陶瓷工业中也可扩大应用。
High silicon high plasticity clay is a high silicon content, plasticity and strong clay, according to its mineral composition, also known as kaolinite - illite - montmorillonite mixed clay. The clay layer occurs in the Lower Middle Jurassic coal measure strata of Jurassic, with ash and off-white sandy mudstone. Ore was dense block, easy to weathering. Ore contains more free quartz. Harmful components are iron. Due to the large amount of montmorillonite contained in the clay minerals except for the chlorite, the clay ore has strong adhesiveness, better plasticity and higher binding force, which is utilized by the porcelain industry and has high industrial value , For the development of large-scale porcelain products has opened up a new rare species of mineral raw materials. And that in the construction, sanitary ceramics industry can also expand the application.
