Titanium 4 Chemical Element Titanium Is A Chemical Element With The Chemical Symbol Ti And Atomic Number 22. It Is Located In The Fourth Period And Group IVB Of The Periodic Table Of Chemical Elements. It Is A Silver-white Transition Metal Characterized By Light Weight, High Strength, Metallic Luster, And Resistance To Moisture Chlorine Corrosion. However, Titanium Cannot Be Used In Dry Chlorine Gas. Even Dry Chlorine Gas With A Temperature Below 0°C Will Undergo A Violent Chemical Reaction To Generate Titanium Tetrachloride, Which Will Then Decompose Into Titanium Dichloride And Even Burn. Only When The Water Content In Chlorine Gas Is Higher Than 0.5%, Titanium Can Maintain Reliable Stability In It. 1/3 Titanium Is Considered A Rare Metal Due To Its Dispersed Presence In Nature And Difficulty In Extraction1. But It Is Relatively Abundant, Ranking Tenth Among All Elements. Titanium Ores Mainly Include Ilmenite And Rutile, Which Are Widely Distributed In The Earth's Crust And Lithosphere. Titanium Also Exists In Almost All Living Things, Rocks, Water And Soil. The Extraction Of Titanium From The Main Ore Requires The Kroll Or Hunter Process. The Most Common Compound Of Titanium Is Titanium Dioxide, Which Is Used To Make White Pigments. Other Compounds Include Titanium Tetrachloride (TiCl4) (used As A Catalyst And Used To Create Smoke Screens For Air Cover) And Titanium Trichloride (TiCl3) (used To Catalyze The Production Of Polypropylene).
