Abstract

A glass-ceramic containing clinopyroxene crystal phase and a preparation method thereof, wherein calcium oxide, iron oxide, boron oxide, silicon dioxide, cerium oxide and antimony oxide are prepared according to a certain chemical ratio and mixed Obtain the batch material evenly; then melt the batch material into molten glass, and keep it warm to clarify and homogenize the molten glass; then pour the molten glass into a heated mold to form it, and quickly transfer it to the Perform precision annealing in the annealing furnace and then cool to obtain calcium-iron-borosilicate glass; finally, cut the glass block into a certain shape, place it on an alumina plate and heat it at the required temperature. After cooling, A glass-ceramic with clinopyroxene as the main crystal phase is obtained. The method has the advantages of simple operation, short preparation period and low cost, and the raw materials used in the preparation process are all environment-friendly, conforming to the concept of green environmental protection; the prepared crystal structure is dense, evenly distributed, and presents a paramagnetic state.

Description

technical field [0001] The invention belongs to the field of preparation of biologically active glass-ceramics, and relates to a glass-ceramic containing triclinic pyroxene crystal phase and a preparation method thereof. Background technique [0002] Glass-ceramics, also known as glass ceramics, is a kind of polycrystalline solid material containing a large number of microcrystalline phases and glass phases, which is obtained by controlling the crystallization of a specific composition of basic glass during the heating process. The comprehensive performance of glass-ceramics is mainly determined by three factors: the composition of the original composition, the size and quantity of crystallites, and the nature and quantity of the residual glass phase. Among them, the original composition is different, and the types of crystal phases are also different, and various crystal phases endow glass-ceramics with different functions. In recent years, with the continuous development ...
