Abstract:
This paper highlighted the advancement in preparation and application technologies of monolithic refractories in recent two decades, in terms of raw materials, processing technology, particle size distribution, binders, additives, workability, installation and applications. Facts and discussions indicated that monolithic refractories are advancing rapidly, from material point of view, towards higher grade and higher performance materials and oxide-non-oxide composites; from installation point of view, towards higher efficiency, less man-power and time consuming techniques; from drying-out point of view, towards quicker or even drying-out free, and from application point of view, towards the working linings of high temperature smelters and vessels under tougher service conditions, and on the other hand, with more functions. 
Key words: Monolithic refractories, Development, Preparation, Application

Abstract :
Sialon multiphase composites containing titanium carbon or titaniumª²nitrogen have been synthesized from clay and additive titania through different sintering processes. The experimental results indicated that there was a great change of crystal phase in the similarb composition specimens sintering in air, nitrogen and bedding protective powder respectively, determined by XRD analysis. The subsequent evidences were also supplied by SEM. The improvement in mechanical properties of multiphase refractories was observed as the amount of titania changing from 0 to 16%. The main causes maybe come from the excellent properties of high hardness and in situ strengthening effects of the in situ formed secondary phase, TiC or TiN.ª¤

Abstract:
Under a firing temperature below 1350¡æ, kiln furniture of high creep resistanceand good thermal shock resistivity has been obtained. The product is composed of mullite cordierite matrix with high alumina bauxite chamottes as aggregate. Thematrix itself is a product of reaction sintering of finely ground kyanite, Suzhou kaolin, calcined alumina and talc. The properties of the samples were measured according to GB standard, and the analyses of the microstructure of the final samples were done by SEM.
Key Words: Kyanite, Mullite cordierite matrix, Creep resistivity

Abstract :
High pure magnesite (MgO¡Ý98%,CaO/SiO₂¡Ý3 with grain size¡Ý50 ¦Ìm) was used as inner layer material and low and middle grade magnesite as out layer material to manufacture magnesia slide plates by means of direct composite, high temperature burning, bonding with waste paper pulp, without pitch impregnation and steel hoop. They were successfully applied in batch in a 385 MT con-casting ladle in a certain foreign steel mill. This paperdescribes the effects of magnesite and burning temperature on high temperature performance and linear change of magnesia slide plates.
Keywords: Composite magnesia slide plate, High pure magnesite, Burning temperature.
