The Relationship

In this paper, the relationship between the creeping effect and mineralogical characteristics of the applied binding phase for various refractory materials (high-alumina materials, with high or low impurity content, tar bonded either magnesite or dolomite materials and silicate bonded chrom-magnesite materials) is presented. The mechanism of creeping is analyzed and the activation energy for creep for each investigated material is obtained and discussed. All investigated materials are creep sensitive under investigated conditions and have similar activation energies for creep except high-alumina refractories with a low impurity content.

Binder Composition

Designed composition of ceramic mass for high-alumina porous permeable ceramic material for disperse micro hydro systems. The filler used alumina fraction 100–250 microns, as a binder system studied refractory clay Veselovskaya–medicalglass–gibbsite. Formation of material carried by dry pressing at a pressure 60 MPa, the temperature of synthesis was 1250–1350 °C, holding at the maximum temperature – 1 h. The processes occurring in the binder during sintering was investigated. The effect of the sintering temperature of the material, the amount of binder composition on the acid resistance, mechanical strength, porosity and permeability of open high-alumina permeable porous material was investigated. The structure and phase composition of the submissions received, the average pore diameter was 10 mm, it can be used for microfiltration of liquids and gases, the material is homogeneous at the macro level, the structure is represented by an extensive network of channels of pores. Phase composition is represented mainly corundum and mullite.
