Problems solved by technology

Chlorine-containing titanium extraction slag has a high chlorine content, so it is difficult to be directly used in building materials. It must be washed and roasted to remove chlorine or add a dechlorination agent to roast to remove chlorine before it can be used, and the added value of the product after dechlorination is low.
[0004] At present, there is no glass-ceramics prepared from titanium slag containing chlorine

Embodiment Construction

[0022] Hereinafter, the glass-ceramic using chlorine-containing titanium extraction slag as the main raw material of the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0023] Chlorine-containing titanium extraction slag is a kind of chlorine-containing low-titanium industrial hazardous slag obtained from titanium-containing blast furnace slag treated by "high temperature carbonization-low temperature chlorination" titanium extraction process. The main components of chlorine-containing titanium extraction slag are CaO, SiO 2 , Al 2 O 3 etc., in line with the main components of the preparation of glass-ceramics, and at the same time it contains TiO that can be directly used as the crystal nucleating agent component of glass-ceramics 2 , Fe 2 O 3 ;Cl in chlorine-containing titanium slag - The content of 2 to 5%, Cl - In the chlorine-containing titanium extraction slag, mainly CaCl 2 Exist in the form, ...

Abstract

The invention provides a glass-ceramic prepared from chlorine-containing titanium extraction slag. The glass-ceramic may include a glass phase and a microcrystalline phase, wherein the microcrystalline phase may include a diopside phase, a feldspar phase, a perovskite phase and a quartz phase. The beneficial effects of the present invention may include: the comprehensive utilization of the chlorine-containing titanium extraction slag can be realized, and the utilization rate of the chlorine-containing titanium extraction slag is more than 85%; the performance of the glass-ceramic is excellent, and the performance is higher than that of natural stone.

Description

technical field [0001] The invention relates to the fields of resource utilization and inorganic non-metallic functional materials, in particular to a glass-ceramic prepared by using chlorine-containing titanium extraction slag as the main raw material. Background technique [0002] Glass-ceramics, also known as glass-ceramics and micro-ceramics, are a kind of polycrystalline material in which the microcrystalline phase and the glass phase coexist by controlling the heat treatment system based on glass and ceramic molding technology. performance, high hardness, high wear resistance and acid and alkali corrosion resistance, etc., can be used as high-grade building decoration materials and various functional materials. The existing raw materials of glass-ceramics include industrial waste residues, tailings, fly ash and the like. Among them, the processes of preparing glass-ceramics from industrial waste residues all have problems such as high energy consumption, long process ...
