An urgent task in the field of creating new functional oxide materials is to obtain products with specified properties for specific requirements, which will expand the field of application of such materials in practice.
The porosity of the materials obtained was calculated.
For porous ceramic materials, it is one of the quality criteria.
The advantages of ferrites that compare favorably with other materials are magnetic resistance [3-5].
Now, the task is to obtain new materials with a spinel structure with superior properties.

Quartz ceramic has a great potential use in engineering ceramic materials.
Introduction Quartz ceramics refer to products which use amorphous SiO2 or fused quartz as raw materials, prepared by traditional ceramic shaping technology.
