Titanium is obtained in the pure form by first treating the oxide with chlorine to form titanium tetrachloride‚ a volatile liquid‚ and then reducing the liquid with magnesium in a closed iron chamber to yield metallic titanium. The metal is then melted and casted.

Notes 1) Introduction • Atoms form bonds to get a full outer shell of electrons • There are three types of bonding: ionic‚ covalent and metallic • The structures produced by forming bonds are either giant or simple • The possible combinations of structure and bonding are giant ionic‚ simple covalent‚ giant covalent and giant metallic • Simple covalent is sometimes called simple molecular • Giant covalent is sometimes called giant molecular or macromolecular • To melt

a thin film of metallic silver that coats the interior of a test tube used. Hypothesis: The silver metal will form on the bottom of the test tube once the aldehyde containing carbohydrate (glucose) reacts with the silver compound. The glucose will be oxidized into an acid while the silver compound will be reduced into metallic silver as the reaction progresses. Data: N/A Analysis: The experiment was a success in the first attempt; the silver nitrate was oxidized into its metallic counterpart. This

Agitated thin film evaporators‚ wiped film evaporators‚ are designed to spread a thin layer or film of liquid on one side of a metallic surface‚ with heat supplied to the other side. The unique feature of this equipment is not the thin film itself‚ falling and rising-film evaporators use thin liquid layers‚ but rather the mechanical agitator device for producing and agitating the

Thus in making CFRP carbon fibre is often combined with polymers such as epoxy to result in a material that has a very high strength-to-weight ratio. Carbon fibre reinforced polymers despite being relative expensive as compared to other traditional metallic materials; they have been preferred for many applications such
