specific Embodiment 1

[0035] Such as figure 1 Shown, a kind of preparation method of microbead ceramic scalpel, comprises the following steps:

[0036] (1), dosing

[0037] Take 1 mass part of zircon and place it in a container, then add 2.5 mass parts of absolute ethanol and 4.6 mass parts of distilled water to the container, then add 0.02 mass parts of yttrium oxide to the container, and stir to obtain a mixed solution ;

[0038] (2) Preparation of xerogel

[0039] Heat the mixed solution obtained in step (1) to 70°C, keep the temperature stable, then add 0.45 parts by mass of ammonia water dropwise to the mixed solution, and keep the mixed solution at 70°C after the white translucent sol is formed until a dry Stop heating after gelling;

[0040] (3) dry

[0041] Washing the xerogel obtained in step (2) with distilled water and absolute alcohol successively, and then drying at 80° C. for 38 hours under vacuum conditions to obtain the dried xerogel;

[0042] (4) Calcination

Description

technical field [0001] The invention belongs to the field of material science and engineering, and in particular relates to a method for preparing a microbead ceramic scalpel. Background technique [0002] At present, the carbon steel scalpels that are widely used in clinical practice have the following disadvantages: easy to rust, poor sharpness, rough surface, negative charge and poor biocompatibility; The effect is poor and so on. [0003] Due to their good biocompatibility and osteoconductivity, bioceramics can show good affinity with biological tissues such as cells, and have long been used in orthopedics, plastic surgery, dentistry, oral surgery, cardiovascular surgery, ophthalmic surgery, Otolaryngology and general surgery. Contents of the invention [0004] Purpose of the invention: the present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the present invention discloses a preparation method of microbead ceramic ...
