Use is claimed as a catalyst for hydrocarbon epoxidation. Use is claimed as a catalyst for hydrocarbon epoxidation of a mixture comprising (A) at least 2 of the following metals: Cu, Ru, Rh, Pd, Os, Ir, Pt, Au, In, Tl, Mn and Ce on (B) a support with a BET surface area ...
a. The act or process of mixing: an alloy made from the mixture of two metals. b. The condition of being mixed: the inevitable mixture of different cultures in big cities. 2. Something produced by mixing, as: a. A combination of ingredients used in cooking or baking. b. One that con...
coarse enough to be distinguished by visual observation. Alloys are mixtures of metals and may be either homogeneous or heterogeneous. The components of a mixture usually can be separated by physical means such as distillation, evaporation, precipitation, filtration, solvent extraction, or chromatography...

According to Gibbs phase rule, n is always equal to or greater than m when the multiphase, multicomponent system has two or more degrees of freedom (i.e. one for the temperature and others for phase saturations); therefore, equation (31) provides a sufficient number of equations to solve ...
Yes. TSCA expressly required the testing of a mixture per se when prior knowledge of its individual components seemed a poor guide to understanding: “If the Administrator finds that … in the case of mixtures, the effects … on health or the environment may not be reasonably and more efficie...
Mixtures Definition - A mixture contains two or more elements or compounds that are not chemically combined together. To learn about Homogeneous and Heterogeneous mixtures click here.
被引量: 2 摘要: A binder is mixed to alumina powder with a purity of 99.5% or more (step S 11 ), the mixture is granulated (step S 12 ), resultant granule powder is formed with a die (step S 13 ), and a formed compact is sintered in a hot-pressing manner (step S 14 )....
In the pyrometallurgical processes, organic electrolytes and binder are burnt off and make leaching of valuable metals more easy (Li et al., 2010a, Freitas et al., 2010, Wang et al., 2009, Chen et al., 2011). In the hydrometallurgical processes, the dismantled electrodes are first ...
