Currently, ceramics based on solid solutions of zirconium dioxide tetragonal structure are common biomedical materials. In commercially common ceramics of orthopedic dentistry based on zirconium dioxide, the stabilization of the tetragonal shape is achieved by the introduction of yttrium or cerium cations. As a result of this scientific work, a ceramic material based on nanopowders of a system of zirconium dioxide and ytterbium oxide with high strength parameters has been developed. The results of the conducted research allow us to recommend the new Yb–TZP ceramics as an alternative to Y–TZP ceramic materials for restorations in orthopedic dentistry.

The results of studies of the structure, phase composition and specific surface of powders based on zirconium dioxide obtained by the method of thermal decomposition of a mechanical mixture of hydroxide and a stabilizing additive are presented. The forming and sintering of ceramic samples obtained from calcined powders, some properties of ceramics were studied. It has been shown that finegrained dense high-strength ceramics with a flexural strength of 860 MPa and microhardness up to 12‒13 GPa can be obtained from the synthesized powders. Ill. 2. Ref. 12.

Zirconium dioxide as core ceramic material for dental crowns and bridges, possess high strength, chemical stability and superior aesthetics after veneering. Veneering ceramic is considered to be the weakest part of all-ceramic restorations. The adhesion between the core and veneering porcelain is based on the manner in which the connection occurs in metal-ceramic structures. Standard procedures for connecting zirconia to hard dental tissues and veneering materials do not achieve the required strength of bonding. The aim of the paper is to investigate different surface treatments of the zirconium dioxide ceramic core and find the best, for achieving highest adhesive bonding values to veneering porcelain. The study was primarily designed to investigate the bonding strength of the veneering porcelain to zirconia with in vitro Macro shear bond strength test. The specimens with different surface treatment of the zirconia were divided in five groups of twelve according to the treatment of zirconium surface and results showed highest bonding values for specimens treated with Rocatec system.

Particulate reinforced Aluminium based metal matrix composites are widely used in aerospace, defense, marine and space applications because their excellent properties such as high strength, high stiffness, high corrosion resistance, high fatigue resistance, high wear resistance etc., In the present work Aluminum Alloy Al6061-Zirconium dioxide composites were developed by stir casting technique by varying the percentage of Zirconium dioxide in steps of 3% up to 12%.The samples were prepared as per ASTM standards for microstructure study, tensile strength and hardness properties. The microstructure studies carried using optical microscope revealed the presence of Zirconium dioxide particulates in the Aluminium matrix. Also it revealed the uniform distribution of Zirconium dioxide in the Aluminium matrix and no voids and porosity were present in the matrix. The tensile strength and hardness properties were more than the base metal aluminium alloy. The tensile strength and hardness properties were increased with the increase in percentage of Zirconium dioxide up to 9% and decreased there afterwards. The optimum value for hardness and tensile strength of the composite was obtained at 9% of Zirconium dioxide.

Metastable beta titanium alloys have been known to have numerous advantages such as cold formability, high strength, good fracture resistance, deep hardenability, and cost effectiveness. Very high strength is obtainable by precipitation of the hexagonal alpha phase in a bcc beta matrix in these alloys. Precipitation hardening in the metastable beta alloys may also result from the formation of transition phases such as omega phase. Ti-15-3 (Ti-15V- 3Cr-3Al-3Sn) has been developed recently by TIMET and USAF for low cost sheet metal applications. The purpose of the present study was to examine the aging characteristics in this alloy.The composition of the as-received material is: 14.7 V, 3.14 Cr, 3.05 Al, 2.26 Sn, and 0.145 Fe. The beta transus temperature as determined by optical metallographic method was about 770°C. Specimen coupons were prepared from a mill-annealed 1.2 mm thick sheet, and solution treated at 827°C for 2 hr in argon, then water quenched. Aging was also done in argon at temperatures ranging from 316 to 616°C for various times.
