If solidification range is an indication of an alloy's tendency to form shrinkage porosity, the copperbismuth alloy should be somewhere between a leaded and unleaded C83600 alloy, Also, deoxidation should reduce the microporosity formation by some small amount.
The corrosion numbers were similar for the deoxidation and conversion-coating processes.
The present study contains the results of experiments carried out to determine the optimum technology of melting special steels and alloys in a AC plasma-arc furnace with a ceramic hearth (10-14) which shows that a decrease of the nitrogen content of the investigated materials takes place at the start of preliminary deoxidation (Figures 6, 7).
The lower need for aluminum deoxidation certainly indicates there is less oxygen being introduced to the metal.
The deoxidation of the slag with the aluminium powder resulted in the complete pickup of titanium and aluminium from the initial metal (Table 2).
The most suitable deoxidation element for the investigated steels is aluminium.

The deoxidation capability of an inoculant is an important characteristic for its successful performance.
In ferrous metallurgy, titanium is used as an alloying element of steel for reducing the grain size and as a deoxidation agent, for reducing the carbon content of stainless steel, and also in many other branches and applications.
The amount of slag or deoxidation products contained in the molten metal will determine the required filtration capacity of the filter.

According to Gupta, the major reasons for the use of silicon carbide in iron foundry melting are low tramp elements, deoxidation capacity, high quality carbon units, improved lining life in coreless furnaces and a reduction in slag-type defects.
