膨润土作为陶瓷的釉料组份应用已久,但在釉料的配方中,膨润土的加入量只占百分之几,它起到粘合剂、悬浮剂的作用,使釉料始终保持足够的稠度和流动性。但是,以膨润土为主料去生产高级瓷,还是初创。材料选择膨润土是以蒙脱石为主要组成的粘土矿物,其化学组成与高岭土相近,只是化学成份中某些元素含量多少不同而已。试验证明,膨润土可作陶瓷原料。但有两大缺点:一是吸水膨胀,吸水后,膨润土可达到它自身体积的8～15倍,它虽易成型,
Bentonite has been used as a ceramic glaze component for a long time. However, in the glaze formulation, the bentonite is added in an amount of only a few percent. It acts as a binder and a suspending agent to keep the glaze at all times Consistency and fluidity. However, bentonite-based materials to produce high-level porcelain, or start-ups. Material selection Bentonite clay minerals are mainly composed of montmorillonite, its chemical composition and kaolin are similar, but the chemical composition of some of the elements of different content only. Test proved that bentonite can be used as ceramic raw materials. However, there are two disadvantages: First, water swelling, water absorption, bentonite can reach its own volume of 8 to 15 times, although it is easy to shape,
