Embodiment 1

[0033] The preparation method of the fluorphlogopite / fluoroapatite glass-ceramic of the present embodiment comprises the following steps:

[0034] 1) Put the fluorophlogopite powder and fluoroapatite powder in the corundum ball milling tank respectively, so that the mass ratio of the two is 9:1, add alcohol and zirconia balls, and carry out wet ball milling and grinding at 300r / min. Mixing: After ball milling for 2 hours, pour the material into a beaker and dry it at 60°C. After the material is fully dried, ball mill it at a speed of 200r / min for 1.5 hours to make the mixture completely powdery and obtain the mixture. Mixed material is crossed 200 mesh sieves again, obtains and gets undersieve;

[0035] 2) Put the undersize material in a graphite mold, apply a pressure of 0.6MPa, and then heat it up to 600°C at a heating rate of 5°C / min. Processing, and surface grinding and polishing, that is.

Embodiment 2

[0038] The preparation method of the fluorphlogopite / fluoroapatite glass-ceramic of the present embodiment comprises the following steps:

[0039] 1) Put the fluorophlogopite powder and fluoroapatite powder in the corundum ball milling tank respectively, so that the mass ratio of the two is 8:2, add alcohol and zirconia balls, and carry out wet ball milling and grinding at 400r / min Mixing: After ball milling for 2 hours, pour the material into a beaker and dry it at 70°C. After the material is fully dried, ball mill it at a speed of 200r / min for 1.5 hours to make the mixture completely powdery and obtain the mixture. Mixed material is crossed 200 mesh sieves again, obtains and gets undersieve;

[0040]2) Put the undersize material in a graphite mold, apply a pressure of 5.0 MPa, and then heat it up to 700°C at a heating rate of 10°C / min. Processing, and surface grinding and polishing, that is.

Embodiment 3

[0044] The preparation method of the fluorphlogopite / fluoroapatite glass-ceramic of the present embodiment comprises the following steps:

[0045] 1) Put the fluorophlogopite powder and fluoroapatite powder in the corundum ball milling tank respectively, so that the mass ratio of the two is 7:3, add alcohol and zirconia balls, and carry out wet ball milling and grinding at 300r / min. Mixing: After ball milling for 1 hour, pour the material into a beaker and dry it at 60°C. After the material is fully dried, ball mill it at a speed of 200r / min for 1.5 hours to make the mixture completely powdery and obtain the mixture. Then the mixture is crossed through a 200-mesh sieve to obtain the under-sieve;

[0046] 2) Put the undersize material in a graphite mold, apply a pressure of 0.6MPa, and then heat it up to 600°C at a heating rate of 5°C / min. Processing, and surface grinding and polishing, that is.

Abstract

The invention relates to fluorophlogite/fluoroapatite glass ceramics and a preparation method thereof and belongs to the technical field of glass ceramics. The method for preparing the fluorophlogite/fluoroapatite glass ceramics includes the steps of evenly mixing fluorophlogite and fluoroapatite to obtain a mixture; hot-pressing the mixture at 600-900 DEG C for 60-120 min, cooling with a furnace,and obtaining the fluorophlogite/fluoroapatite glass ceramics. According to the preparation method, the sintering temperature is reduced to be within 900 DEG C, the ultra-high temperature process ofa traditional casting method is omitted, the controllability of material properties is effectively ensured, the requirements on production devices are significantly reduced, and the production processis simplified. The preparation method greatly reduces the manufacturing difficulty, facilitates industrialized production, saves energy, is environmentally friendly and is a very promising fluorophlogite/fluoroapatite glass ceramics preparation method.

Description

technical field [0001] The invention relates to a fluorphlogopite / fluoroapatite glass ceramic and a preparation method thereof, belonging to the technical field of glass ceramics. Background technique [0002] As a new type of inorganic material, glass ceramics have good mechanical properties and excellent chemical stability. Glass-ceramics is controlled crystallization of the mother glass under a certain heat treatment system, thereby uniformly growing a large number of microcrystals, and finally forming a polycrystal in which ceramic and glass phases coexist. The performance of glass ceramics mainly depends on the composition and quantity of crystal phase and glass phase, so it has the advantages of both glass materials and ceramic materials and becomes a special composite material. There are many types of glass ceramics, among which mica glass ceramics have been extensively studied in recent years. Due to their excellent bioactivity, biocompatibility, and unique processa...
