Microwave-plasma treatment of the material was carried out in the presence of the following materials: charcoal, coal/quartz and molybdenum sulfide.
In papers [18, 22, 23] a method of microwave exposure on various materials was proposed in order to change the phase composition and to activate the surface of materials.

Introduction The application of biomedical materials for repair of bone defects has involved significant research in the field of biomaterials science with the aim to achieve faster and better biological healing outcomes.
Materials and Methods Synthesis, granule reparation and sintering of calcium phosphates was done according to the procedure published before [5, 6].
Biphasic calcium phosphate materials can be used as bone grafting material to strengthen osteoporotic bone and to improve bone healing [11].

Therefore, the first left-handed materials come out to human being [2].
In 2003, the founding of left-handed materials has been selected as one of the “ten key” scientific breakthrough by American <<Science>> magazine, which triggered worldwide research on this new artificial material.
With development of the research, the left-handed materials expanded to the multi-functional materials called metamaterials [3].
That’s to say, metamaterials, which are the new artificial materials that are not found in nature, can control the path of electromagnetic wave’s transmission.
