4 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Introduction Opportunity in refrigerators: improvement of the magnetic force reducing the material cost

5 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Introduction(cont.) Mexico is one of the principal raw magnetic material producer of BaCO 3 & SrCO 3 (Nuevo León y Coahuila)

6 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Antecedents The magnetic Materials are relevant in many appliances (electric motors, microwave ovens, refrigerators, washers), automotive & aeronautic industry

7 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Antecedents (cont.)

8 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Antecedents(cont.) However the cost to produce strong field magnetic is too expensive (Sm o Nd) http://www.aimangz.com/web_programa/global/gtd_lista_subfamilia.php?familia=smco&subfamilia=barra Prices in Euros

9 Av. Del Retablo No. 118-B Col. La Era Querétaro, Qro. C.P. 76150 Tel. (442) 214-4767 Email: contacto@centronacionalfem.com Antecedents(cont.) Barium ferrite magnets are cheap, but the magnetic field is relatively weak. http://www.aimangz.com/web_programa/global/gtd_lista_subfamilia.php?familia=smco&subfamilia=barra Prices in Euros
