Triiron tetraoxide

Chemical-transport reactions have been used to prepare single crystals of triiron tetraoxide (magnetite) and other ferrites, which comprise the majority of all known ferrimagnetic mate-... 

Procedure to perform several adiabatic oxidatively-heating tests, which are started from each T, with mutual intervals of 1 2 K, in order to calculate the heat generation data of a moisture-containing gas-permeable oxidatively-heating substance, such as natural product, e.g., sawdust or triiron tetraoxide, for 2 cm each of several samples of the substance charged each in the draft cell, into which air is supplied, for the time. At, required for the temperature of each sample of the substance to increase by the definite value of AT of 1.25 K from the corresponding standard temperature, respectively...
