#### **Abstract**

The last chapter of this book provides brief description of utilization of apatites and phosphorus-bearing compounds in industry and material science research. Since the chemistry of phosphorus is quite complicated and a quickly developing field of science, the topics described below are only limited insights to chemically bonded ceramics and refractories, dental phosphate cements, oil-well cements, phosphate glasses and glass ceramics. Chapter continues with description of functional phosphate materials applied as solid oxide fuel cells electrolytes, sensors, phosphors, catalysts and coatings. The chapter ends with introduction of basic ideas for biological apatite in bone tissue engineering, collagen apatite composites, apatite layers and biocoatings.

In the previous chapter, the utilization of phosphate ore was described. Elemental phospho‐ rus (**Section 9.1**) and phosphoric acid (**Section 9.2**) are used in the manufacturing of other phosphorus compounds (as illustrated in **Fig. 1**) and materials, which are briefly reported in this chapter. Since the chemistry of phosphorus is quite complicated and a quickly develop‐ ing field of science, the topics described below are only limited insights to phosphorus-bearing compounds utilized in the industry and material science research.
