2. 1. Chemical reactions in aluminium electrolytic capacitors

   Author : Ildiko Szaraz; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Abstract : Aluminium electrolytic capacitors are used in a wide variety of different applications. The aluminium electrolytic capacitor consists of two aluminium foils wound together and separated by special paper, which is impregnated with an electrolyte. READ MORE

4. 2. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

   Author : Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

   Abstract : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).

5. 3. Antimony recovery from complex copper concentrates through hydro- and electrometallurgical processes

   Author : Samuel Ayowole Awe; Olof Forsén; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Today, one of the major difficulties confronted during copper metallurgy is the elimination of antimony and arsenic impurities from the process. This is because the pure copper ore reserves are becoming exhausted and the resources of unexploited ores often contain relatively high amounts of antimony and arsenic. READ MORE
