Calcium is added in the steel ladle furnace (LF) in the form of CaSi wire to modify inclusions and to desulphurize steel. The range in which all the oxides become liquid and no solid sulphides begin to form is regarded as the "optimum window" or “liquid inclusion
The relative density of magnesium is 1.74 g/cm 3 , which is two-thirds the density of aluminum, and typical magnesium alloys weigh 35% less than their aluminum counterparts at equal stiffness  . Their high strength-to-weight ratio makes magnesium alloys extremely promising for appliions requiring light weight, such as aerospace and transports  .

nesium-containing aluminum alloys. Mechanism of spinel When compared to stoichiometric spinel, the alumina-rich spinels have additional vacant lattice sites with the capability to absorb low- melting, low-viscosity components of the attack-ing slag, such as
Regardless of the Ca and Si content, the solidifiion of the aluminum-magnesium alloys ends with the following nonvariant eutectic reaction: L → (Al) + Al4Ca + Mg2Si + Al3Mg2. With respect to the temperature and composition of the liquid phase, this reaction is close to the eutectic reaction in the Al-Mg binary system.
In this processing ensures optimum degassing, removing oxides and receiving slag with low aluminum content (picture 7). Without applying flux such rotary treatment is not as effective for the removal of oxides and, Moreover, leads to the formation of slag with a high content of aluminum (drawings 8 and 9).
Thus, failing paint adhesion can be one indiion that the conversion coating process is less than optimum. BAC5765 PSD 9-11 - Cleaning and Deoxidizing Aluminum Alloys. 9. Boeing SR/PA 632-100, 1978. 10. Boeing Memo 6-4620-F1-98024, 7/29/1998.
Calcium phosphate ceramics for use in implants are introduced and various methods of producing calcium phosphate coating on titanium substrates are elaborated. Advantages and disadvantages of each type of coating from the view point of process simplicity, cost‐effectiveness, stability of the coatings, coating integration with the bone, cell behavior, and so forth are highlighted.

Under optimum processing conditions, with lead temperature between 1040 to 1110 F and an efﬁcient vortex method of addition, typical recoveries are calcium 85-95% and aluminum 75-85%. At 90% and 80% recovery, the calcium-aluminum ratios in the
Steel and foundry products - ferro alloys and recycling The Steel and Foundry Industry Business Unit of Treibacher Industrie AG specializes in the manufacture and worldwide sale of ferro alloys In the steel industry, ferro alloys are used as aggregates to modify and improve the properties of steel.
Procedures are described for the analysis of bismuth-base alloys containing 0.2 to 5% of uranium and 0.2 to 5% of neodymium or praseodymium. Bismuth is first separated from a solution of the alloy in 1 N nitric acid by extraction with diethylammonium diethyldithiocarbamate in chloroform, followed by the separation of uranium with the same reagent from an acetate buffered solution of pH 5.5 to 6.0.
Calcium carbide is a powerful and effective chemical reducing agent, and can also be used as a source of energy. Nowhere is this more evident than in the field of metallurgy, where it is used in several ways to reduce costs. In modern steelmaking operations, the

potential as a phase component in aluminum alloys because of its high melting temperature (1085 o C), low density (1.99 g/cc), high hardness (4.5 GPa), low coefficient of thermal expansion (7.5 x 10 -6 K -1 ), and reasonably high elastic modulus .
Calcium aluminate flux is used for steel refining in integrated plants based on iron ore processing as well as in mini-mill based on scrap recycling. The main use is in secondary metallurgy in coination with lime, ferro-alloys and possibly other minerals.
Being a relatively cheap element, calcium improves the properties to a maximum degree and is optimum with respect to the cost. However, it should be noted that when contained in an amount exceeding 0.3%, calcium worsens the casting properties and decreases the ductility of magnesium alloys.
