It is produced by a sinter process and provides the same homogeneous product properties which are well known for other established sintered aggregates such as tabu-lar alumina and sintered spinel. This paper presents the properties of the new refractory aggregate and laboratory results of refracto-ries based on it. The new aggregate provides an alternative to oth-er high alumina
Calcium aluminate cement is a kind of refractory material and binder which can not only be used as castable refractory but also be used in monolithic refractory as binding agent. For instance, it can be used as the binder of high alumina castable, corundum castable, mullite castable, and other castable refractory. As a refractory material
BSA 96 NEW EUROPEAN SINTER AGGREGATE WITH 96 % Al 2 O 3. BSA 96 is a new synthetic dense aggregate with 96 % Al 2 O 3. It is produced by a sinter process and provides the same homogeneous product properties which are well known for other established sintered aggregates such as tabular alumina and sintered spinel.
This invention provides an alumina base ceramic sintered body excellent in wear resistance with high hardness, also with high strength and high toughness, and particularly suitable for a cutting tool or wear resistant member. This sintered body contains 5-70 % by volume of WC and 5-70 % by volume of Ti (C,N) solid solution
REFRACTORY MOLDS FOR GLASS SINTERING Recovered container glass can be formed into marketable products by filling a refractory mold with powdered glass and heating the glass and mold to a high temperature so that the glass sinters (or bonds) to take the shape of the mold. The process creates high value-added uses for recovered
With increase in alumina content sinter productivity and tumbler index (T.I.) decreased, and metallurgical properties like sinter RDI and reducibility improved. However, sinter of the selective granulation process showed better results compared to the conventional process.
Also high purity caustic calcined magnesia is used in both the sintering or electrofusion process for the production of alumina-magnesia spinels used in basic refractories and special castables. In addition high purity CCM is used as feedstock for the production of premium grade refractory fused magnesia.
This research was conducted to develop new formulations of AZS (alumina-zirconia-silica) refractories with different amounts of ZrO2 with the purpose of improving properties and the work conditions in the glass melting furnaces and, at the same time, lower the costs this type of refractories.
But changes in the refractory raw materials market over the past few years have influenced the properties of the currently available synthetic high alumina materials and triggered the development of new aggregates. The purpose of this paper is to outline the differences between high alumina fused and sintered raw materials. The focus will be
