Embodiment 1

[0036] Embodiment 1: the preparation of oxygen suspension CST5 black bioglass

[0037] (1) Mixing: 9.4758g of calcium silicate and 6.5422g of titanium dioxide are mixed in an agate mortar and rubbed with alcohol for three times;

[0038] (2) Tablet calcining: get 2g of uniformly mixed powder and put it into the abrasive tool and put it on the tablet press to pressurize 2Mpa, hold the pressure for 1 minute, and press it into a cylindrical tablet with a diameter of 20cm; Calcined at 1000°C in a Furnace and kept warm for 5 hours to obtain a ceramic sheet (the ceramic sheet after calcination is still white and has no photothermal effect);

[0039] (3) Air-suspension firing: cut the calcined sample (ceramic sheet) into small pieces and put it into an air-suspension laser heating furnace. The top of the sample is heated to form a spherical melt, and the sample is heated and cooled repeatedly by laser to remove air bubbles. After the sample is homogenized, the laser is turned off, a...

Abstract

The invention relates to black bioglass as well as a preparation method and an application thereof. The preparation method of the black bioglass comprises the steps as follows: (1) weighing silicate and TiO2 in the molar ratio to serve as raw materials and mixing the raw materials to obtain mixed powder, wherein in terms of 100% of the sum of the molar percentages, the molar ratio of silicate to TiO2 is (40%-90%):(10%-60%) and silicate is at least one of akermanite and CaSiO3; (2) pressing the obtained mixed powder into a sheet, and calcining the sheet to obtain a ceramic chip; (3) placing theobtained ceramic chip in a container-free air suspension furnace to be heated by laser to be in a molten state and performing quick cooling to obtain the black bioglass.

Description

technical field [0001] The invention discloses a black biological glass and its preparation method and application, in particular to a multifunctional black glass containing titanium silicate, which belongs to the field of inorganic material preparation technology and biological materials. Background technique [0002] Due to its good biocompatibility and bioactivity, bioglass has been widely used as bone tissue scaffold material in the field of tissue engineering. The traditional methods of synthesizing biological glass materials can be divided into: melting method and sol-gel method. The earliest bioglass 45S5 was prepared by melting method. The traditional fusion method utilizes a quenching route to make silicate glass. It is characterized by simple process and wide application range, but there is the possibility of equipment corrosion and crucible pollution in high temperature environment, resulting in lower glass purity, and smaller surface area than bioglass, lower b...
