Abstract

The invention relates to ferrimagnetic foam microcrystalline glass and a preparation method thereof. The ferrimagnetic foam microcrystalline glass is prepared by uniformly mixing waste glass powder and a ferrimagnetic crystal forming agent and then carrying out one-step heat treatment crystallization foaming, and the ferrimagnetic crystal forming agent is composed of carbon powder and Fe2O3. CO gas generated by reduction reaction of the carbon powder and the ferric oxide at the glass softening temperature forms bubbles in the glass, and meanwhile, the ferric oxide is reduced into ferroferric oxide ferromagnetic crystals. The ferrimagnetic foam microcrystalline glass provided by the invention is a novel porous glass functional material, and has dual functions of a traditional foam glass thermal insulation material and a novel magnetic wave-absorbing material. The waste glass, the carbon powder and the ferric oxide are adopted as raw materials, the raw materials are easy to obtain and low in cost, high-added-value recycling of the waste glass is achieved, and the method has the dual significance of environmental protection and economy.

Description

technical field [0001] The invention relates to a ferrimagnetic foam glass-ceramic and a preparation method thereof, belonging to the technical field of foam glass production. Background technique [0002] As a transparent, safe, non-polluting, high-strength green product, glass has been widely used in people's daily life and is becoming more and more popular. Glass is also a brittle material, which will inevitably break and lose its function during use. At the same time, when glass is used as a packaging container, the glass packaging container loses its preservation value when the packaged items are consumed. Therefore, most glass tends to lose its use value and become waste glass, and one of the characteristics of glass products as green products is its recyclability. In the currently implemented domestic waste classification table, the first category of recyclable waste is glass. There are several types of recycling of glass products, such as flux for casting, transfo...
