Here again we have an evidence of organic action; for it is the deoxidizing power of vegetable matter which has in all the later formations been the efficient cause in producing bedded deposits of iron.
Now we know of no agency existing in present or in past geological time capable of deoxidizing carbonic acid, and fixing its carbon as an ingredient in permanent rocks, except vegetable life.
Before deoxidizing the ore, it is requisite to expel the water and carbonic acid combined with the oxide, as well as the sulphur of the pyrites.
As we have seen, the removal of sulphur can be made complete only by deoxidizing calcium, and this cannot be done if much oxygen is present.
This same strong deoxidizing action leads to the practically complete deoxidation and hence extraction of the iron.
But the strong deoxidizing conditions needed in the blast-furnace to remove sulphur tend strongly to deoxidize silica and thus to make the pig iron rich in silicon.
The strong deoxidizing action incidental to this carburizing removes the sulphur easily and cheaply, a thing hardly to be expected of any direct process so far as we can see.
We can picture to ourselves how in the first period the savage smith, step by step, bettered his control over his fire, at once his source of heat and his deoxidizing agent.
A beautiful example of suchdeoxidizing action on a non-argentine compound has lately occurred to me in the examination of that interesting salt, the ferrosesquicyanuret of potassium described by Mr. Smee in the Philosophical Magazine, No.
There can be no doubt that the process, in a great majority, if not in all cases, which have been noticed among inorganic substances, is a deoxidizing one, so far as the more refrangible rays are concerned.
Moreover, the solution is immediately decolourised by sulphuretted hydrogen and other deoxidizing agents, as well as by alkalies and many acids.
Tungsten Blue is an oxide formed by the action of various deoxidizingagents on tungstic acid.
The heat is withdrawn from the air and employed in deoxidizing the carbonic acid.
The slag changes from black to white as the metallic oxides are reduced by these deoxidizing additions and the reduced metals return to the bath.
The deoxidizing slag is now formed by additions of lime, coke and fluorspar (and for some analyses ferrosilicon).
In addition, they may be added to metallic fusions, fordeoxidizing and also to communicate to the commercial alloys (such as bronze, brass, etc.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "deoxidizing" in a variety of sentences. We hope that you will now be able to make sentences using this word.
