Technical field
The present invention relates to a kind of preparation method of sintered glass, particularly a kind of simple method for preparing of sintered glass.
Background technology
Sintered glass has vesicular structure, can be widely used in insulation, filter and photoelectric field.The sintered glass of different pore size and porosity can be prepared according to the actual requirements, there is lower density and heat insulation function, can be used as material of construction; Also by controlling pore size and opening and closing situation, as support of the catalyst, fluid purification filtration etc.Sintered glass introduces gas in solid glass, reduces the specific refractory power of glass, creates the energy bandgaps affecting light and propagate, and can be used as the covering of optical fiber.In addition, sintered glass as base material, can also introduce nano-metal particle in micropore, cause quantum confined effect, Dielectric confinement effect etc., improve the non-linear optical property of glass, can be applicable to optical storage, transmission and switch etc., is the major parts of optoelectronic device.
Current sintered glass preparation method is mainly split-phase method and sintering process.Split-phase method need through processes such as melting, phase-splitting, acid treatment, and the kind of glass is mainly limited to the glass that borosilicate etc. can produce phase-splitting, and the treatment time is long, complex process.Sintering process, mainly through adding whipping agent in the feed, sinters under lower than the temperature of fusion of glass, and the sintered glass transmittance therefore prepared is low, can not be used as optics.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art shortcoming, the simple method for preparing that a kind of technique is simple, be suitable for wide, the transparent sintered glass of glass types is provided.
