Abstract
The present invention discloses glass ceramics, and a production method and a dedicated device therefor. Glass ceramics are prepared by using tantalum-niobium tailings, blind mining of natural stone material is greatly reduced, and comprehensive utilization efficiency of tantalum-niobium tailings is improved. The glass ceramics obtained by the production method and the dedicated device has few bubbles and high strength, and the yield and the quality of the finished product are both improved. Moreover, the idle tantalum-niobium tailings are utilized in the production, so that resources are saved.
