Essay

The object for study is layer ceramic materials with protective coatings of Nb2O5, Ta2O5, LiNbO3. The purpose is complex studies for development of new materials and articles with protecting coatings; disign of special equipment. Methods of studies are the tests of layer ceramic specimens by a method of a temperature cycling; dilatometric, metallographic, X-ray phase analysis; microprobe technique; spectral and weight analysis; the test of articles in industrial conditions. Novelty - Materials changing platinum in the thermochemical treating of high purity niobium compounds are developed. It is finded out the negative heat expansion fiеld of fused Ta2O5 specimens as well as the concentration SiO2 influencing on the Nb2O5 a crystallisation in alloys of variable composition (Nb2O5) х - (SiO2)1-x. It was worked out and realized the physicochemical principles the high purity pellet production of niobium oxide and niobate lithium. It is recommend the developed materials and articles of them at the plants which are produce high purity niobium and tantalum compounds.
