Calcium carbide is used as a desulfurizer, dehydrant of steel, fuel in steel making, powerful deoxidizer and as a source of acetylene gas. It is used as a starting material for the preparation of calcium cyanamide, ethylene, chloroprene rubber, acetic acid, dicyandiamide and cyanide acetate.
In this work, experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag, simultaneously. As calcium carbonate is precipitated in a solution containing ammonium chloride, calcium chloride

It is found in many chemical compounds, one of the most familiar of which is the main constituent of limestone. There are many important industrial uses for calcium. It is used as a deoxidizer in the refining of iron, steel, copper, and copper alloys .
Naming Binary Ionic Compounds with a Metal That Forms More Than One Type of ion If you are given a formula for an ionic compound whose ion can have more than one possible charge, you must first determine the charge on the ion before identifying its correct name.
Zinc fluoride is used in the fluorination of organic compounds, in the manufacturing of phosphors for fluorescent lights, in preserving wood, in electroplating baths, in galvanising steel, and making ceramics. It is also used as a termite repellent, in mediion, and
Guide for the Use of Steel Slag in Agriculture and for Reclamation of Acidic Lands Introduction This guide discusses the use of steel slag, a co-product of the steel making process, as a substitute for limestone for agricultural appliions, and its use in reclamation
Calcium is used to deepen firework colors. Calcium salts produce orange fireworks. Cl Chlorine Chlorine is an important component of many oxidizers in fireworks. Several of the metal salts that produce colors contain chlorine. Cu Copper Copper compounds Fe
The main stages The main steps in making steel are shown on the left. You can find more information about each step by clicking on it. In this section we’ll summarise the chemistry that is important in changing iron ore into steel. Reactivity of metals Iron is a
Calcium (Ca)(Z = 20) Calcium is a very commonly used element of the alkali earth metal family. It has been in use for as long as can be dated back even before its official discovery by an English Chemist Humphry Davy (1778-1829) in 1808. It had been in use in
Although there have been a numerous nuer of studies on mathematical model of hot metal desulfurization by deep injection of calcium carbide, the research field as a whole is not well integrated. This paper presents a model that takes into account the kinetics, thermodynamics, and transport processes to predict the sulfur levels in the hot metal throughout a blow. The model could be utilized
Important Compounds of Magnesium and Calcium Several magnesium compounds occur naturally, either in mineral form or in brine. These include the carbonate, chloride, hydroxide, and sulfate. Other magnesium compounds can be prepared from these. The following are important magnesium compounds and their uses: MgO - Refractory furnace linings, a component in ceramics and cement; …
