Problems solved by technology

[0002] In 1997, Pinckney and Beall developed nano-glass ceramics with great economic value, but most glass-ceramics have large crystal diameters and are basically opaque. The main application and research fields of glass-ceramics are in the high-silicon area, that is, the silicon dioxide content is 60%. Above, it is more difficult to melt the refractory material with high silica content
[0003] Most of the existing nano-self-assembly technologies can only produce nano-particle materials, nano-membrane materials, and nano-liquid materials, but cannot produce nano-bulk materials.

Abstract

The invention discloses a transparent nanocrystalline glass and its preparation method. The transparent nanocrystalline glass is prepared by one or two of silicon oxide, aluminium oxide, zinc oxide, magnesium oxide, zirconium oxide, titanium oxide and potassium oxide, and sodium oxide, one or more of neodymium oxide, erbium oxide, antimony oxide, cobalt oxide, ferric oxide, nickel oxide, chromium oxide. The preparation method includes steps of evenly mixing and stirring raw materials; ball milling, melting, casting, annealing, nucleating and crystalizing the raw materials to obtain the transparent nanocrystalline glass. The silicon dioxide content in the transparent nanocrystalline glass has middle and low silicon, the melting is easier by reducing the content of refractory material silicon dioxide; the crystal diameter is situated between 1-100 nanometers, and the glass has the surface effect, small dimension effect and macroscopic quantum tunneling effect which are owned by nanometer materials only; meanwhile, the application field is widened for the transparent nanocrystalline glass is transparent. Based on above characteristics, the transparent nanocrystalline glass has extensive application prospect.
