“…Generally, the spinel can be synthesized by an electrofusion method, a sintering method and a mechano-chemical method (Kashcheev and Semyannikov 2000;Dasgupta et al 2006;Lodha et al 2008), and the porous structure can be achieved by a conventional powder-processing route with the incorporation of some pore-forming agents, or * Author for correspondence (yanwenref@yahoo.com.cn) by injection molding or gel casting (Xie 1998;Liu et al 2001;She and Ohji 2003). Porous alumina ceramics were prepared by decomposition of Al(OH) 3 to form pores in situ (Deng et al 2001).…”

The porous spinel ceramics were prepared from magnesite and bauxite by the pore-forming in situ technique. The characterization of porous spinel ceramics was determined by X-ray diffractometer (XRD), scanning electron microscopy(SEM), mercury porosimetry measurement etc and the effects of particle size on microstructure and strength were investigated. It was found that particle size affects strongly on the microstructure and strength. With decreasing particle size, the pore size distribution occurs from multi-peak mode to bi-peak mode, and lastly to mono-peak mode; the porosity decreases but strength increases. The most apposite mode is the specimens from the grinded powder with a particle size of 6•53 μm, which has a high apparent porosity (40%), a high compressive strength (75•6 MPa), a small average pore size (2•53 μm) and a homogeneous pore size distribution.

In this study, novel MgO-C refractories using environmentally friendly sucrose as binder were prepared. To solve the harmful effects of formaldehyde and phenolic compounds that cause serious harm to the environment and human health released during the development, production and use of phenolic resin binders for MgO-C refractories, MgO-C refractories using environmentally friendly sucrose instead of phenolic resins as binders were prepared. The phase, microstructure, oxidation resistance and the antioxidant mechanism of MgO-C refractories prepared by adding sucrose as binder at different temperatures were analyzed. The formula between the weight loss of the material and the temperature is y=1.6225x+0.215 (600°C ∼ 1200°C). The addition of aluminium resulted in the formation of Al2O3 inside the refractories. Meanwhile, MgAl2O4 crystals were synthesized by Al2O3 and MgO at high temperature. The formation of Al2O3 and MgAl2O4 played an important role in improving the oxidation resistance property of MgO-C refractories using sucrose as binder.
