Abstract

A device for measuring the magnetization of a soft ferrite pre-sintering material is provided. The device comprises a weighing mechanism, a bracket above the weighing mechanism, and a support on the top of the bracket, wherein the support is provided with a permanent magnet, the weighing mechanism connected with the inside of the bracket is provided with a container for holding a ferrite pre-sintering material. The bracket, the support and the container are all non-magnetic structures. The device indirectly measures the amount of spinel by measuring a magnetization angle, is high in measurement accuracy of magnetization, simple, reasonable, easy to process and manufacture, and convenient to operate. Components in the device are common in laboratories and low in cost so as to reduce research and development and production cost, help to improve production efficiency, and help to ensure high product quality.

Description

technical field [0001] The invention relates to the field of soft ferrite powder testing, in particular to a device for measuring the magnetization degree of soft ferrite calcined material. Background technique [0002] In the preparation process of soft ferrite materials, pre-calcination is a key process, which is pre-calcined at a temperature lower than the sintering temperature, which plays a key role in ensuring the stability and quality consistency of subsequent production. The pre-fired powder has partially produced ferrite, but it is not complete, and it needs to be sintered to produce all ferrite. [0003] The pre-firing temperature has a certain influence on the optimum sintering temperature, and the pre-firing and sintering processes must match to achieve the desired effect. The choice of pre-firing temperature and the amount of ferrite generated have a great influence on controlling the shrinkage rate and deformation of the product and determining the sintering t...
