Tungsten Oxide

As we all know, the main raw material of glass is silica, namely quartz, the main raw material of ceramics is kaolin. Coincidentally, the main component of tungsten tailings is also silicon, and may be rich in other kaolin constituents. In the eyes of scientists and technicians, most of the composition of tungsten tailings and glass ceramic raw materials are similar, do not need too complicated to deal with, can be processed into glass ceramic. Some scholars have prepared glass ceramics by using tungsten tailings after magnetic separation to remove iron, by changing the temperature system in sintering process, the glass ceramics with better properties were obtained, and the crystallization kinetics of glass-ceramic during sintering was further explored. The crystallization temperature is adjusted between 950~1100 °C, the results show that the main crystalline phases of glass ceramics are calcium feldspar and iron pyroxene. The crystalline phase number and grain size o...

Tungsten tailings are the wastes left in the production of mines. China is a big producer of tungsten resources. It is said that all large tungsten mines have a large number of tailings reservoirs, and the tailings reservoirs accumulated over several decades or even centuries have become too large to imagine. Some tailings which have reached the marginal grade can be extracted again, but most of the tailings are no longer meaningful. How to find a way out for these tailings? Tailings treatment has always been a thorny problem in mining enterprises, not only copper and iron, tungsten ore also racking their brains for tailings to find a new way out, the most common tungsten tailings application is the manufacture of cement, tile. However, with the development of industrial technology, people found that it is a waste that tungsten tailings are used to make cement and bricks. In recent years, scientists have invented a material between ceramic and glass, which has remarkable func...
