23 Jul Preparation process of calcium phosphate bone biomaterial
Abstract
The invention discloses a preparation process of a calcium phosphate bone biomaterial. The preparation process comprises the following steps: taking a compound containing calcium ions and a compound containing phosphorus ions as raw materials, the raw materials are weighed according to the chemical metering ratio of corresponding elements in the formula of Ca<3>(PO<4>)<2>, ground and then evenly mixed; the mixture is pre-calcined under the air atmosphere, ground and evenly mixed, wherein the pre-calcination temperature is 400-600 DEG C, and the calcination time is 1-10 hours; the mixture is continuously calcined in the air atmosphere, ground and evenly mixed, and then the powdery material is obtained, wherein the calcination temperature is 800-900 DEG C, and the calcination time is 2-8 hours. A preparation method is simple, the synthesis temperature is low, and energy consumption is reduced; and the prepared product has good biological activity and can be used as a bone tissue engineering or dental material. The material prepared by the method is easy to collect, the operating process is environmentally friendly, and the preparation process is suitable for being applied and popularized in the industry.
