Abstract

The invention discloses a preparation method of a high-strength glass material. The preparation method comprises the following steps: a, mixing TeO2, K2O, SiO2, Tm2O3, Yb2O3, Fe2O3, Er2O and Bi2O3, putting the mixture into a ball mill, and performing ball milling to obtain a material I; b, drying the material I, putting the dried material into a mixing furnace, and mixing to obtain a material II; c, guiding the material II into a mould, and clarifying to obtain a material III; d, annealing the material III, and cooling to room temperature. The glass material prepared by the preparation method provided by the invention has good fracture resistance and relatively high Vickers hardness, and the application range of the glass material can be significantly widened.

Description

technical field [0001] The invention belongs to the technical field of glass materials, and in particular relates to a preparation method of high-strength glass materials. Background technique [0002] With the wide application of glass products in the fields of industry, medicine and buildings, the existing demand for glass is not limited to blocking and transmitting light. More is the demand for good mechanical strength of glass, such as good fracture resistance and high hardness. However, due to the poor mechanics of the glass itself due to its own internal structure, the improvement of glass preparation components has increasingly become the subject of people's attention. [0003] In the prior art, when increasing the hardness of glass, lead oxide is often added to obtain glass with high hardness, good wear resistance and good fracture resistance. However, the addition of lead oxide will have a negative impact on the human body and the environment, so for excellent Env...
