In order to study the background of the quality control which affects the quality rate of Mn-Zn ferrite, tests have been made on the mechanism of deformation and the dimensions of core, related to the linear shrinkage during sintering.
It has been shown that in compacting and cutting process, the core dimensions may be determined with a view of expansion after compacting, and compacting techniques affect the deformation seriously, but the rate of elevating furnace temperature has no influence on the deformation of product.
And it has been suggested that the dewax mechanism has relation to the deformation of product.
The linear shrinkage of Mn-Zn ferrite is depend on recrystallization or crystal growth rather than the reaction of the spinel formation during its sintering.
