Biphasic calcium phosphate ceramics (BCP) comprising a mix of non-resorbable hydroxyapatite (HA) and resorbable beta-tricalcium phosphate (beta-TCP) are particularly suitable materials for synthetic bone substitute applications. In this study, HA synthesised by solid state reaction was mechanically mixed with beta-TCP, then sintered to form a suite of BCP materials with a wide range of HA/beta-...

The study discusses how the process information reserves can be used for improving production flexibility on basis of component variation control. Building upon assumption that data in question describe functions components as those experience perturbations, we submit it may possible to predict productivity and economic efficiency new, previously unused control options. We elaborate ensure flex...

There exist complex chemical reactions and phase transition processes—melting solidification—in the iron ore sintering process. This will result in bed shrinkage has an important impact on process sinter properties. Numerical simulation was carried out this paper, it is based porous medium double-energy equation model, coupled with porosity model. The influence of explored revealed by comparing...

In connection with future utilization of magnetite titanium ores deposited in Poland in the region of Suwałki the test were performed to get information regarding the influence of titan and vanadium admixtures on the quality of pig iron and the run of blast furnace process. As a blast furnace charge, there were used magnetite titanium concentrates similar to the ores deposited in the Suwałki re...
