Porous Cordierite

Highly porous cordierite ceramic by using of talcum, kaolinite and γ-alumina was obtained by method of slip casting of concentrated suspension. Additives of amorphous silica and non-stabilized zirconia in the amount of 5 wt% were used. Sintering temperature of dried samples was in range of 1250 – 1450°C. All the samples contain crystalline phases of cordierite, mullite and corundum but, depending on the additives, as a result of sintering in addition forms spinel, cristobalite or zircon (ZrSiO4). Porosity of obtained materials changes in large scale from 42 to 59 per cent; it is influenced by both sintering temperature and composition. Compressive strength increases with the addition of zirconia. In comparison, compressive strength of samples without additives or with silica additive does not exceed 3.5 MPa. The increase of coefficient of thermal expansion depends both on the composition and sintering temperature. ZrO2 additive increases the coefficient of thermal expansion considerably.

The investigating results are given on the cordierite ceramic porous materials development. The wood waste and the crystalline carbamide were used as the pore-formers. The pore structure analysis showed that all samples had complex pore space composed of numerous elongated connected pores. The best pore formation factors were achieved when using the organic crystalline pore-former. It was demonstrated that nanodispersive metal alumina acted as the strengthening agent in course of the porous ceramics sintering. The organic clay suspension improves the cordierite powder's agglomeration capacity and gives rise to additional nano- and micro-pores.

Porous cordierite is among the special porous ceramic due to its extensive properties. In this research, porous cordierite was fabricated through gelcasting method. A mixture of raw materials (SiO2, Al2O3 and MgO) was melted at 1550 °C followed by quenching in water to produce a glass. Then the formed glass powder were milled for 1, 3, 5, 7 and 9 hours to obtain various particle sizes of cordierite powder. Cordierite powder produced was then used to prepare 3-D porous cordierite ceramic using gelcasting method. The cordierite pellets were characterized. Surface morphology was analysed via Scanning Electron Microscope (SEM) to observe the pore structure of porous cordierite formed from powder with various particle sizes.

Using X-ray diffraction analysis and infrared spectroscopy techniques, the effect of additives on phase composition variation during mechanochemical activation of a kaolin-containing cordierite batch was investigated. It was shown that introduction of Trilon B permits fixing of the start of cordierite synthesis already during batch activation. It was established that mechanochemical activation of a cordierite batch doped with Trilon B results in an increase of the strength of cordierite samples prepared by polymer matrix duplication.
