High densities of point and lattice defects, as well as a fine dispersion of reactants, are introduced in the powder mixture during MA. In addition, the displacement <span style=\"color:red\">reaction</span> in the Fe-CuO system produces a large negative heat. This combination of factors makes the redox <span style=\"color:red\">reaction</span> occur in the <span style=\"color:red\">reaction</span> regions, accompanied by self-heating. The self-heating may raise the temperature up to ignition temperature for a combustion <span style=\"color:red\">reaction</span>; this ignition temperature is greatly decreased by ball-milling. Combustion then takes place. The displacement <span style=\"color:red\">reaction</span> may be carried out rapidly during combustion. Complete reduction of copper oxides, including the intermediate oxidation <span style=\"color:red\">state</span> phase, Cu2O, appearing immediately after combustion, is observed after prolonged milling, during which the reduction is gradual; a similar self-sustaining <span style=\"color:red\">reaction</span> mechanism works in local <span style=\"color:red\">reaction</span> regions.","authors":[],"categoryName":"|","doi":"","fpage":"189","id":"2a981d9f-4dc1-420b-8cb2-6938000e8f8d","issue":"2","journal":{"abbrevTitle":"MSAEAMPMAP","id":"29fa6a83-07f2-4d3a-af3e-fac686227352","issnPpub":"0921-5093","publisherId":"MSAEAMPMAP","title":"Materials Science and Engineering a-Structural Materials Properties Microstructure and Processing"},"keywords":[{"id":"a5daf094-5fcd-420e-ae9c-ac17654d3e22","keyword":"amorphous-alloys;powders","originalKeyword":"amorphous-alloys;powders"}],"language":"en","publisherId":"0921-5093_1992_2_3","title":"<span style=\"color:red\">SOLID-STATE</span> DISPLACEMENT <span style=\"color:red\">REACTION</span> OF FE AND CUO INDUCED BY MECHANICAL ALLOYING","volume":"151","year":"1992"},{"abstractinfo":"<span style=\"color:red\">Solid</span> <span style=\"color:red\">state</span> <span style=\"color:red\">reaction</span> of Mg with Ni was processed under static high pressure and nanocrystalline Mg2Ni was obtained.

It also shows that there is no change happened on the cubic crystal structure even though a little amount of Ce(3+) ion added to the powders can lead to the lattice distortion of BaHfO(3) matrix material. The excitation spectrum of BaHfO(3): Ce nanoparticles has two excitation peaks separately at 396 nm and 446 nm points. The emission spectrum excited by the 396 nm light consists of two emission bands, peaking at 531 nm and 591 run, respectively, the emission character of which changes from the 5d ->(2)F(5/2) to 5d ->(2)F(7/2) transitions of Ce(3+) cation. When the emission spectrum is excited by the 446 nm light, only one wide emission peak at 591 nm point exists and the other one at around 531 nm becomes flat. When the Ce(3+) dopant content is 0.9%(molar fraction), the figure of the emission peak reaches its highest point. This figure, however, drops when The Ce(3+) dopant content is 1.1%( molar fraction), which is resulted from the concentraction quenching.","authors":[],"categoryName":"|","doi":"","fpage":"1248","id":"e3d4c177-5c01-4f37-8471-ffe67de95e36","issue":"7","journal":{"abbrevTitle":"CJOIC","id":"ebb2aa1b-ce1f-4f04-b1bd-f890ca4f71dd","issnPpub":"1001-4861","publisherId":"CJOIC","title":"Chinese Journal of Inorganic Chemistry"},"keywords":[{"id":"a9be05b1-e174-4b2a-a797-6603ba4585ee","keyword":"scintillant;BaHfO(3):Ce nanoparticles;<span style=\"color:red\">solid-state</span> <span style=\"color:red\">reaction</span> process;excitation spectrum;emission spectrum;combustion synthesis;photoluminescence;phosphors;y2o3-eu;ca;sr;ba;nanophosphors;fabrication;ceramics","originalKeyword":"scintillant;BaHfO(3):Ce nanoparticles;solid-state reaction process;excitation spectrum;emission spectrum;combustion synthesis;photoluminescence;phosphors;y2o3-eu;ca;sr;ba;nanophosphors;fabrication;ceramics"}],"language":"en","publisherId":"1001-4861_2009_7_1","title":"Preparation and Luminescence Characteristics of BaHfO(3):Ce Nanoparticles by the Process of <span style=\"color:red\">Solid-State</span> <span style=\"color:red\">Reaction</span>","volume":"25","year":"2009"},{"abstractinfo":"The <span style=\"color:red\">solid-state</span> <span style=\"color:red\">reaction</span> between crystalline nickel and pulverized melt-spun amorphous Fe78Si12B10 powders during mechanical milling has been investigated.
