Carbon nano-tube/aluminum oxide biological ceramic and preparation method thereof
The invention discloses carbon nano-tube/aluminum oxide biological ceramic and a preparation method thereof and belongs to the field of biomedical materials. The carbon nano-tube/aluminum oxide biological ceramic is prepared from, by mass, 55.0-75.0 parts of nanometer aluminum oxide, 5.0-10.0 parts of carbon nano-tubes, 3.5-5.5 parts of 300-mesh zircon flour, 1.5-3.0 parts of nanometer tin oxide, 2.0-4.5 parts of magnesium phosphate, 1.0-2.5 parts of yttrium oxide, 2.0-5.0 parts of barium sulfate and 1.1-1.9 parts of tantalum pentoxide. The preparation method of the carbon nano-tube/aluminum oxide biological ceramic includes the following preparation steps of 1, material preparation, 2, premix preparation; 3, vacuum calcination, 4, step-by-step cooling, and 5, taking out after cooling. According to the carbon nano-tube/aluminum oxide biological ceramic, the good compressive strength and abrasive resistance and excellent biocompatibility of aluminum oxide biological ceramic are kept, meanwhile, bending resistance and breaking tenacity are further improved, and the carbon nano-tube/aluminum oxide biological ceramic can be more widely applied.
