Problems solved by technology

However, the preparation and color development process of copper-red glass is very complicated, the process control is not easy, and the preparation technology is immature, which limits its application in glass decoration.
Especially copper red glass colorant Cu 2 O is easy to oxidize, and the preparation needs to control the atmosphere in the kiln to be a reducing atmosphere, which greatly increases the cost of the kiln and the difficulty of melting qualified copper-red glass

Abstract

The invention provides copper ruby glassware and a process for preparation thereof. Weight components of the copper ruby glassware comprise: SiO2 holding 70-75 parts, CaO holding 7-12 parts, Na2O or K2O holding 15-22 parts, Cu2O holding 0.4-2.0 parts, SnO holding 0.4-3.0 parts, active carbon powder holding 0.1-2.0 parts, CeO2 or Sb2O3 holding 0.005-0.1 parts and NaSiF6 holding 0.5-1.0 parts. The invention induces copper nano-particles in glass to produce and precipitate, and is low in cost and simple in process, capable of realizing not only integral coloring of the glass, but also local coloring of the glass, which facilitates mass production.

Description

(1) Technical field [0001] The invention relates to a copper-red glass product and a preparation method thereof, in particular to a method for preparing copper-red glass products by using ultraviolet light to excite and induce the precipitation of copper nanoparticles in glass. (2) Background technology [0002] Glass materials containing nanoscale metal particles have attracted great attention and interest due to their unique optical properties. Due to the surface plasmon resonance of metal nanoparticles in glass, there are obvious optical nonlinear phenomena near their characteristic absorption peaks. Therefore, in the data It has great application potential in optoelectronic devices such as storage, optical waveguide, and optical switch. With the development of large-scale integrated microelectronics and optoelectronics technology towards higher integration and three-dimensional integration, the construction of controllable three-dimensional microstructure units with opto...
