摘要:
The present invention relates to a magnesium-based alloy, and to a method for producing same. The method comprises the steps of: melting a magnesium alloy into a liquid state; adding a silicon compound to said molten magnesium alloy; exhausting the silicon compound through a full reaction between said molten magnesium alloy and said added silicon compound such that the silicon compound does not substantially remain in the magnesium alloy; and exhausting the silicon produced as a result of said exhaustion in the precious step such that the silicon may not substantially remain in said magnesium alloy.

Methods of preparing an aromatic liquid crystalline polyester resin and an aromatic liquid crystalline polyester resin compound are disclosed. A method of preparing an aromatic liquid crystalline polyester resin may include: acetylating a first monomer including an amino group by a reaction with a carboxylic acid anhydride; acetylating a second monomer including a hydroxyl group and not including an amino acid group with an additional carboxylic acid anhydride; and synthesizing an aromatic liquid crystalline polyester prepolymer by a condensation polymerization reaction of the acetylated first and second monomers with dicarboxylic acid. A method of preparing an aromatic liquid crystalline polyester resin compound may use the aromatic liquid crystalline polyester resin prepared according to the forgoing method.
