Fluxes Sentence Examples
In making up a charge, the ores and fluxes, whose chemical compositions have been determined, are mixed so as to form out of the components, not to be reduced to the metallic or sulphide state, typical slags (silicates of ferrous and calcium oxides, incidentally of aluminium oxide, which have been found to do successful work).
Magnetic induction, like other fluxes such as electrical, thermal or fluid currents, is defined with reference to an area; it satisfies the same conditions of continuity as the electric current does, and in isotropic media it depends on the magnetic force just as the electric current depends on the electromotive force.
Aided by grants from the Prussian government, these workers systematically investigated the effect of introducing a large number of different chemical substances (oxides) into vitreous fluxes.
The bullion left in the retorts is then melted in black-lead crucibles, with the addition of small quantities of suitable fluxes, e.g.
No evidence of smelting ores with fluxes is offered, but casting from metal melted in open fires is assumed.
Platinum is employed in oxidizing processes, and in the fusion of substances with fluxes; also in observing the colouring effect of substances on the blowpipe flame (which effect is apt to be somewhat masked by charcoal).
In Lake county, for example, very much of the argentiferous ore that is too low for remunerative extraction (limit 1903 about $12.00 per ton) is used for fluxes.'
The coarse-metal is now smelted, with coke and siliceous fluxes (in order to slag off the iron), and the product, consisting of an impure copper sulphide, is variously known as " blue-metal," when more or less iron is still present, " pimplemetal," when free copper and more or less copper oxide is present, or " fine " or " white-metal," which is a fairly pure copper sulphide, containing about 75% of the metal.
Ores containing gold or silver are almost invariably assayed in the dry way; that is, by fusion with appropriate fluxes and ultimate separation of the elements in the metallic form.
In some processes of lead-smelting, where the minerals treated contain sand, the long calciner is provided with a melting bottom close to the fire-place, so that the desulphurized ore leaves the furnace as a glassy slag or silicate, which is subsequently reduced to the metallic state by fusion with fluxes in blast furnaces.
AdvertisementWhen coupled with sonic anemometry, fast response sensors can provide information on atmospheric fluxes, as well as gas concentrations.
The high temperatures generated fuse the ore particles and fluxes together to form a porous clinker called sinter.
Observational methods, e.g. eddy correlation techniques to measure turbulent fluxes or measurement of mean profiles to infer turbulent transport.
The primary goal is to quantify accurately the global air-sea fluxes of CO 2.
Use water as a solvent, either in combination with detergent to remove rosin flux residues or in conjunction with water soluble flux residues or in conjunction with water soluble fluxes.
AdvertisementIon fluxes related to growth of plantation forestry are considered.
Recent observational evidence indicates a systematic reduction in gravity wave fluxes in the upper mesosphere and lower thermosphere from solar minimum to solar maximum.
Flux.A common event in the exudation of turbid, frothing liquids from wounds in the bark of trees, and the odours of putrefaction and even alcoholic fermentation in these are sufficiently explained by the coexistence of albuminous and saccharine matters with fungi, yeasts and bacteria in such fluxes.
In the pamphlets written concerning the sale by Dr William Cockburn (1669-1739) of his secret remedy for dysentery and other fluxes, it was stated for the defence that Sloane himself did not disdain the same kind of professional conduct; and some colour is given to that charge by the fact that his only medical publication, an Account of a Medicine for Soreness, Weakness and other Distempers of the Eyes (London, 1745) was not given to the world until its author was in his eighty-fifth year and had retired from practice.
Pottery vessel sinks are made by merging a blend of clays, fillers, and fluxes together in a firing process.
