What is kroll process used for the purification of metals?
The Kroll process is used to purify titanium metal. It involves reducing titanium tetrachloride with magnesium to produce titanium and magnesium chloride. The magnesium chloride is then removed, leaving behind purified titanium metal.
Why is titanium so exspensive?
Titanium is corrosion resistant, very strong and has a high melting point. It has a relatively low density (about 60% that of iron). It is also the tenth most commonly occurring element in the Earth's crust. That all means that titanium should be a really important metal for all sorts of engineering applications.In fact, it is very expensive and only used for rather specialised purposes.Titanium is used, for example:in the aerospace industry - for example in aircraft engines and air frames;for replacement hip joints;for pipes, etc, in the nuclear, oil and chemical industries where corrosion is likely to occur.Why is titanium so expensive?Titanium is very expensive because it is awkward to extract from its ores - for example, from rutile, TiO2.You can't use carbon reductionTitanium can't be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle.That means that you have to use an alternative reducing agent. In the case of titanium, the reducing agent is either sodium or magnesium. Both of these would, of course, first have to be extracted from their ores by expensive processes.Other problemsThe titanium is produced by reacting titanium(IV) chloride, TiCl4 - NOT the oxide - with either sodium or magnesium. That means that you first have to convert the oxide into the chloride. That in turn means that you have the expense of the chlorine as well as the energy costs of the conversion.Titanium(IV) chloride reacts violently with water. Handling it therefore needs care.Traces of oxygen or nitrogen in the titanium tend to make the metal brittle. The reduction has to be carried out in an inert argon atmosphere rather than in air. That also adds to costs.High temperatures are needed in both stages of the reaction.Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something.With titanium, however, you make it one batch at a time. Titanium(IV) chloride is heated with sodium or magnesium to produce titanium. The titanium is then separated from the waste products, and an entirely new reaction is set up in the same reactor. This is a slow and inefficient way of doing things.Titanium extractionConversion of titanium(IV) oxide, TiO2, into titanium(IV) chloride, TiCl4The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about 900°C.
Can you balance the equation TiCl4 plus Na Ti plus Na Cl?
Here is the balanced equation! TiCl4 + 2H2O --> TiO2 + 4HCl
What ion name is PbCI?
lead IV chloride
What row is titanium on in the periodic table of elements?
Titanium is in the fifth horizontal row on the periodic table. It is in the fourth group on the table as well.
How do you extract titanium from its wore?
The ore rutile (impure titanium (IV) oxide) is heated with chlorine and coke at a temperature of about 900°C. Then the Titanium chloride is reduced using Magnesium and distilled to get rid of the Magnesium chloride (Magnesium atoms displaced titanium atoms). Then you get titanium.
Word Equation for titanium reacting with chlorine?
Ti + Cl2 -> TiCl2 Ti + 3/2Cl2 -> TiCl3 Ti + 2Cl2 -> TiCl4
What is TiCl4 name?
Titanium chloride or Titanium dichloride or dichlorotitaniumResponse to the answer above:It is Titanmium Dichloride. There are two chlorine bonded to titanium that's acting as the central atom.It would be Titanium Chloride if there was one Chlorine bonded to one Titanium. BUT its a 1:2 ratio, which rules out Titanium Chloride.Dichlorotitanium isn't even possible. Titanium is the positive atom not to mention the central atom so therefore its the first "in line" so to speak to be named, then comes whats attached to it.EXMAPLE: CO2 is Carbon Dioxide, because 2 Oxygen Molecules are attached to 1 Carbon. And because Carbon is the positively charged atom (like Titanium) its named first, which is why its not called Dioxycarbon.
