By trial the XRF analysis method for determination of silicon and calcium in silicon-calcium alloy is worked out.

Effects of Si-Ca Alloy on Microstructure and Mechanical Properties of Mg-6Al-0.5Mn Alloy;

The analyzing method for measuring Si and Ca elements in Si-Ca alloy are studied by using inductance coupling plasma emission spectrum instrument.

In the paper the Si-Ca alloy was smelted with mixed charging method using Jinchuan Corporation\'s waste nickel slag and calcined lime as the major materials,charred coal and charcoal as reducing matter in self-made miniature DC arc furnace.

Influence of the content of Sn-Ca on the corrosion resistance in Pb-Ca alloy;

Pb-Ca alloy normal substances used for direct-reading spectrometer;

The features, production process and problems related to the production of Pb-Ca alloy were described.

Effect of Silicocalcium on the Casting Properties of AM60 Alloy;

The process of silicocalcium production in a 3.

It discusses the physicochemical principle of producing silicocalcium and introduces four kinds of domestic and foreign techniques,such as,mixing process,two-step process,slicing process and electro-silicothermic process.
