Chemical Composition Stability of Corundum/Zirconium Dioxide Composites in a Biological Media
Abstract—This paper studies the chemical composition stability of modified 1 mol % CaO ceramic composites which contain 50 mol % Al2O3 and 50 mol % [12Ce–TZP] or 50 mol % [3Yb–TZP] and are produced from powders synthesized by a hydrolytic sol-gel method. It is shown that the content of dangerous elements, such as As, Be, Cd, Cr, Pb, and Sb, in the new composites is below the maximum allowable limits. In addition, this paper establishes the high stability in the chemical composition of the composites after a long presence in a media that simulates the conditions of the body. The mass loss for Al is no more than 5 × 10–4 wt %; for Zr, it is no more than 1 × 10–4 wt %.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
