1Sintering — is a method used to create objects from powders. It is based on atomic diffusion. Diffusion occurs in any material above absolute zero but it occurs much faster at higher temperatures. In most sintering processes the powdered material is held in… …
2advanced ceramics — ▪ ceramics Introduction substances and processes used in the development and manufacture of ceramic materials that exhibit special properties. As is pointed out in the article ceramic composition and properties, ceramics are… …
3Ceramic engineering — Simulation of the outside of the Space Shuttle as it heats up to over 1,500 °C (2,730 °F) during re entry into the Earth s atmosphere Ceramic engineering is the science and technology of creating objects from inorganic, non metallic… …
4CÉRAMIQUES INDUSTRIELLES — Si la céramique est à coup sûr l’une des premières formes d’expression de l’intelligence humaine, elle reste souvent mal connue dans son ensemble. L’origine de son nom prête à des indications erronées dans de nombreux ouvrages. «Céramique» dérive …
5Powder metallurgy — is the process of blending fine powdered materials, pressing them into a desired shape (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process generally… …
6Nanoparticle — In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. Particles are further classified according to size[1] : in terms of diameter, coarse particles cover a range… …
7POUDRES (MÉTALLURGIE DES) — La métallurgie des poudres est aussi ancienne que l’art des potiers et des céramistes. Cependant, ce qui n’était que techniques ancestrales purement empiriques s’est transformé en une discipline scientifique dans les années 1930, dès qu’on a… …
8Frittage — Le frittage est un procédé de fabrication de pièces consistant à chauffer une poudre sans la mener jusqu’à la fusion. Sous l effet de la chaleur, les grains se soudent entre eux, ce qui forme la cohésion de la pièce. Le cas le plus connu est… …
9Verre fritté — Frittage Une pièce de métal fritté. Le frittage est un procédé de fabrication de pièces consistant à chauffer une poudre sans la mener jusqu’à la fusion. Sous l effet de la chaleur, les grains se soudent entre eux, ce qui forme la cohésion de la… …
10traditional ceramics — Introduction ceramic materials that are derived from common, naturally occurring raw materials such as clay minerals and quartz sand. Through industrial processes that have been practiced in some form for centuries, these materials are made …
