EXTRACTING TITANIUM

• WHY IS TITANIUM USEFUL?

  strong, low density, high melting point
• WHAT IS TITANIUM USED IN?

  aerospace industry, hip joint replacements
• WHAT ARE MOST METALS FOUND AS NATURALLY?

  oxides
• HOW ARE MOST METALS USUALLY EXTRACTED?

  by reacting with carbon to produce metal and carbon dioxide
• GENERAL FORMULA FOR EXTRACTION OF A METAL OXIDE?

  metal oxide + carbon -> metal + carbon dioxide
• WHY CAN TITANIUM NOT BE EXTRACTED BY REACTING WITH CARBON?

  would form TiC which is brittle
• HOW IS TITANIUM EXTRACTED?

  1. Reacted with chlorine and carbon to produce TiCl4 + CO
  2. Reduced by Mg
• EQUATION FOR TITANIUM EXTRACTION?

  TiCl4 (l) + 2Mg (s) -> 2MgCl2 (s) + Ti (s)
