The advanced bioceramics production using process of vibroturbulization

Michael Shoikhedbrod


Currently, bioceramics are widely used in medicine as dental and bone implants. Surgical bioceramics are used regularly. Joint replacements are usually coated with bioceramics materials to reduce wear and tear and inflammation. Pacemakers, kidney dialysis equipment, and respirators are more instances of bioceramics being used in the medical field. The production process of bioceramics consists of the following four main steps: preparation of powder with a grain size of not more than 100 nm, mixing, shaping, compaction and finishing. The existing known methods of mixing do not allow obtaining promising bioceramics of uniform raw (unfired) density, since paddle mills are mainly used for mixing ceramic materials. Raw material powder particles and various impurities or sintering additives added to bioceramics powders, the distribution in the bioceramics material (usually one clay or one or more clays) during processing is critical for advanced bioceramics, and advanced bioceramics products must be uniform, completely dense, with high physical and chemical properties. This article presents a completely new mixing method in the main production process of advanced bioceramics. In the developed method, the mixing of particles, powder grains and various alloying or sintering additives injected into ceramic powders leads to their uniform distribution in the ceramic material, forming an unfired mixture of uniform density, due to vibration in the vibroturbulization process mode
