METHOD OF MAKING BARIUM STRONTIUM TITANATE FILLED PLASTICS

摘要

A method is designed to make a plastic product capable of absorbing electromagnetic waves. The method comprises a first step in which a Barium Strontium Titanate powder is formed of aqueous solutions of titanium oxalate strontium oxalate, and barium oxalate. The barium Strontium Titanate powder is then mixed with a plastic organic compound to form a mixture, which is heated at a temperature corresponding to the melting point of the plastic organic compound, thereby resulting in formation of a molten mixture. A plurality of strips are formed of the molten mixture by extrusion. The strips are cut into granular pieces capable of absorbing electromagnetic waves of low and intermediate frequencies.
