The Chelyabinsk Zinc Plant (an enterprise of the UMMC metallurgical complex) received a conclusion from the French laboratory EAG on the conformity of the quality of the produced high-purity indium of 6N qualification according to the international standard ASTM B1002-16 and the In0000 brand according to GOST 10297-94. Chemical analysis was carried out by the method of mass spectrometry with ionization in a glow discharge (GD-MS).
“The obtained certificate allows us to sell high-purity indium, including on the European market,” notes the commercial director of the Chelyabinsk Zinc Plant Alexander Kharchenko ... - The purity of the metal is 99.9999%, in the foreign classification it is the 6N grade, that is, "6 nines".
In0000 is used in the semiconductor industry. Indium of special chemical purity has the property of remaining efficient at low temperatures. This property allows it to be used in powerful cryogenic installations.
