In this paper, under the direction of environmentally friendly theory, we study on thecalcium hydroxide and hydroxyapatite from the aspects of controlling pollution fromheadstream and manufacturing with the idea of bionics.At firstly, We try to producing calcium hydroxide particles in the polyacralamidewater solution, using in situ synthesis method. Some methods(i.e.scanning electronmicroscopy (SEM), Fourier transform infrared spectroscopy(FTIR), Transmissionelectron microscopy(TEM), X-ray diffraction spectroscopy(XRD) were used to find thatcalcium hydroxide encapsulated by PAM. In this way, this kind of calciumhydroxide-PAM hybrid material became more difficutly in reacting with carbon dioxideand the diameter of hybrid material could be controlled under nano-meter. When thishybrid material was used in the plastic industry, it would decrease the toxic waste duringthe combusting process. Some high energy-cost modifying agents can also be replaced bycalcium hydroxide-PAM to increase mechanicl function.Secondly, with changing drying material on the substrate, we can obtain dentriticflower calcium hydroxide-PAM hybrid material with dentritic flower shape. The SEM,XRD, TG-DTA revealed that production has all properties of Friendl'salt which could beused in many field such as catalyzed industry.Finally, simulating the environment and process of organisms producingself-material, biological materials with uniques structures and morphologies have beenproduced. With special concentration of ions (maganisum, aluminum, strontium)additives in the solution, the products have different morphologies.This kind of specialshapes would hopely be used in plastic industry and used as a bone substitute material.
