Description
Technical Field
The invention belongs to the technical field of glass preparation, and particularly relates to a method for preparing glass from refractory or infusible materials.
Background
Glass is an old and modern material, and is an important basic material necessary for the development of the high-tech industry at present. With the continuous development of science and technology, the application of glass materials is more and more extensive and more important. With the continuous maturity of glass manufacturing technology and the more and higher performance requirements of people on glass materials, the need for finding more glass materials is more urgent.
Glass can be obtained by different methods, such as melt-quenching, sol-gel, chemical deposition, and mechanical ball milling. The most common method in glass production is still the melting-quenching method, wherein the raw materials are heated to the temperature above the melting point to obtain high-temperature melt, and then the long-range disordered structure of the melt is subjected to 'freezing' by the quenching method to obtain the glass. However, in the search for new glass materials, we have found that conventional glass making methods have not been able to meet the production requirements of today's so many types of glass materials. For example, some refractory, infusible materials have a relatively low decomposition temperature and cannot be heated to a molten state and decomposed directly, or can not be made into glass by a melt-quenching process. The variety of refractory, infusible materials that can be made into glass by sol-gel, chemical deposition or mechanical ball milling is very small, and these methods tend to require long production times and expensive production equipment.
Disclosure of Invention
In order to broaden the preparation method of the glass material and reduce the preparation cost of the glass, the invention provides a novel preparation method of the glass, namely, firstly inducing the crystal to be converted into the amorphous state (structure collapse) by a pressure or hot pressing method, and then heating the amorphous structure to induce the glass-transition. For refractory, infusible materials that cannot be made into glass by the melt-quenching process, pressure-induced amorphization followed by vitrification by heating-quenching is an ideal method. Compared with the existing sol-gel method and chemical deposition method, the method has simple preparation process and low requirements on preparation conditions and preparation equipment.
The scheme of the invention is as follows:
a method of forming a glass from a refractory or infusible material comprising the steps of:
(1) pressurizing or hot-pressing the refractory and infusible materials to make the materials amorphous, wherein the hot-pressing temperature is lower than the decomposition temperature of the refractory and infusible materials;
(2) heating-quenching the non-crystallized material obtained in the step (1) to prepare the glass, wherein the heating temperature is higher than the glass transition temperature and lower than the decomposition temperature of the refractory and infusible material.
Preferably, the refractory, infusible material is UIO-66, aluminate or quartz.
The invention has the beneficial effects that:
the invention provides a method for vitrifying refractory and infusible materials, which is an important supplement of the existing glass preparation method and provides possibility for vitrifying refractory and infusible materials and preparing different types of novel glass. Meanwhile, the glass preparation method provided by the invention can improve the mechanical property of the glass, reduce the glass preparation temperature and achieve the effect of saving energy.

Detailed Description
The technical solution of the present invention is not limited to the specific embodiments listed below, and includes any combination of the specific embodiments.
Example 1 (non-melting Material for vitrification)
UIO-66 is an organic-inorganic hybrid material which decomposes directly when heated and has not been reported to be vitrified.
A method of making glass from a refractory or infusible material comprising the steps of: the UIO-66 was tabletted and placed in a vacuum autoclave at 50MPa, heated to 350 ℃ at a rate of 5 ℃/min, held for 60min and furnace cooled. Then transferring the glass to a common muffle furnace for 5 ℃/min, heating to 400 ℃, preserving heat for 30min, and carrying out water quenching and cooling to obtain UIO-66 glass. The UIO-66 glass is shown in FIG. 1. As can be seen from FIG. 1, the UIO-66 glass prepared by this method had a pronounced glass luster.
Example 2 (vitrification of refractory component)
The aluminate glass plays a vital role in the aspects of infrared guidance and information transmission as an important medium-wave infrared material. However, the preparation of large-sized aluminate glass has a problem of low yield due to the relatively high melting point and poor glass forming ability of the aluminate glass.
In this example, C12A7 (12 CaO 7 Al)2O3) For the object of study, CaO and Al were first mixed2O3According to a molar ratio of 12: 7, uniformly mixing in a ball mill, tabletting, placing in a hot pressing furnace with the pressure of 1Gpa, heating to 1350 ℃ at the heating rate of 10 ℃/min, preserving the heat for 60min, and cooling along with the furnace. Then transferring the aluminate solution into a muffle furnace, heating to 1200 ℃ at a speed of 10 ℃/min, preserving the temperature for 60min, and cooling along with the furnace to obtain the aluminate glass. The aluminate glass prepared by the method has high yield, and the hardness of the prepared aluminate glass is 7.6 GPa.
Example 3 (vitrification of refractory component)
Quartz glass is one of the widely used oxide glasses, and is generally commercially produced by oxidizing SiO2The powder was heated to 1900 deg.c to prepare quartz glass.
In this embodiment, SiO is first introduced2Tabletting the powder, placing in a hot-pressing furnace with a pressure of 50Mpa, heating to 1750 ℃ at a heating rate of 10 ℃/min, preserving heat for 60min, and cooling with the furnace. Then transferring the quartz glass to a common muffle furnace, heating to 1400 ℃ at a speed of 10 ℃/min, preserving heat for 30min, and cooling along with the furnace to obtain the quartz glass. The quartz glass prepared by the method has the hardness of 7.2GPa and the elastic modulus of 89.2 GPa, and is improved compared with the quartz glass (the hardness is 6.8GPa and the elastic modulus is 73.9 GPa) obtained by a melt quenching method.
