✦ Synopsis

The in6uence of ball milling and subsequent calcination of a 2.5:1 molar mixture of -Fe 2 O 3 and Li 2 CO 3 on the formation of lithium ferrites has been investigated. Premilling was found to considerably lower the temperature at which the lithium ferrites LiFeO 2 and LiFe 5 O 8 are formed. A -to--phase transition in LiFe 5 O 8 was found to take place on cooling from ca. 10003C depending on the milling history and cooling regime. 2002 Elsevier Science (USA)

The aim of this work was to investigate the crystallographic structure, size distribution and chemical composition of FINEMET type powders after long milling (20 h up to 1800 h). Three different powder samples have been prepared and investigated: the first one by milling of amorphous ribbon with a c

The exact mechanism of irradiation-induced occlusion of normal or abnormal retinal vessels is still to a large extent obscure. Blood flow acts as a powerful heat dissipation mechanism. Therefore, a procedure which reduces flow velocity as rapidly as possible after the beginning of irradiation may wo
