Embodiment Construction

[0022] Aiming at the development and utilization of the titanium-containing magnetite tailings in Panzhihua, the present invention directly uses the vanadium-titanium magnetite tailings as the raw material for the production of glass-ceramics according to the composition characteristics of the vanadium-titanium magnetite tailings, with high content of TiO 2 It is a crystal nucleating agent and fluxing agent with excellent performance. The glass composition contains CaO, MgO, Al 2 O 3 , Fe 2 O 3 Mainly introduced by tailings, basically no external addition; additional SiO 2 In order to reduce the relative content of CaO and MgO, improve the crystallization performance of glass, because SiO 2 It is a glass network forming body, which is the main component, and the content cannot be too low; but it cannot be too high, and the viscosity of the glass will increase if it is too high.

[0023] The key to making glass-ceramics from Panzhihua titanium-containing magnetite tailings is to us...

Abstract

This invention provides a glass ceramic produced by debris of magnetite that contains titanium. it takes titanium-containing debris as the main raw material, plus quartz sand that SiO2 purity greater than 96% and content of 18% ~ 30%; With further increase feldspar that content of 2% to 5% as additives; the weight percentage of above glass ceramic composition: SiO2: 55 ~ 65, Al2O3: 4 to 10, CaO: 10 ~ 20, MgO: 3-7, TiO2: 4 to 7, Fe2O3: 4.0 ~ 9.5, ZrO2: 0 ~ 1.5 , K2O - Na2O: 4 to 9. This invention can comprehensive utilize of titanium containing vanadium and titanium magnetite debris, can effectively solve the problem of environmental and safety issues caused by the long-term accumulation of debris, and reduce production costs.

Description

Technical field [0001] The invention relates to a technology for applying titanium-containing tailings of vanadium-titanium magnetite to building decoration materials to produce glass-ceramics, and in particular to a glass-ceramic made of titanium-containing magnetite tailings. Background technique [0002] Glass-ceramic is a new material with high strength (bending resistance, compression resistance), hardness, corrosion resistance (acid resistance, alkali resistance) and abrasion resistance developed artificially in recent decades, also known as artificial granite (Or marble). Mainly used in construction decoration, metallurgy, chemical industry, machinery, ceramics, medicine, astronomical telescope and other industries and departments. When used as a building decoration material, it has a texture similar to natural stone, beautiful and elegant, resistant to atmospheric corrosion, light in texture and easy to process. In addition, it is possible to produce interior and exterior...
