Vol. 98, nr 2

56--85

Purpose: Among the technologies that play a crucial role in the current stage of development of Industry 4.0 conventional powder engineering technologies are of great importance. Based on a comprehensive literature review, conventional technologies using the powders of metals, their alloys and ceramics are described. Development perspectives of the most widespread among them were indicated. Design/methodology/approach: Extensive literature studies on conventional powder engineering technologies have been carried out. By using knowledge engineering methods, development perspectives of individual technologies were indicated. Findings: In addition to the presentation of conventional sintering technological methods, sintering mechanisms in solid-state and liquid phase sintering which accounts for 90% of the commercial value of sintered products are presented. Originality/value: According to augmented holistic Industry 4.0 model, many materials processing technologies and among them conventional powder engineering technologies play a key role in current industry development. For this reason, these technologies have been characterized in detail on the basis of available literature sources.

W pracy przedstawiono wyniki wytwarzania mullitu o składzie wyjściowym (3Al2O3 · 2SiO2) syntezowanego z tlenku glinu o uziarnieniu nanometrycznym oraz amorficznego dwutlenku krzemu. Otrzymane wyniki porównano z efektami syntezy mullitu z surowców o uziarnieniu mikrometrycznym. Spieki mullitu, otrzymane w różnych temperaturach syntezy badano pod względem jakościowego i ilościowego składu fazowego (metoda dyfrakcji rentgenowskiej XRD), jak również zbadano mikrostrukturę z użyciem skaningowej mikroskopii elektronowej (SEM). W artykule dokonano interpretacji wyników i określono wpływ uziarnienia substratów na zastosowaną temperaturę syntezy.

The paper presents interpretation of results mullite the base composition (3Al2O3 · 2SiO2) which have been synthesized from nanometer size alumina and amorphous silicon dioxide. The results were compared to the effects of the mullite synthesis from micrometer size raw materials. Obtained at different temperatures of synthesis, sintered bodies have been analyzed under qualitative and quantitative phase composition (XRD) and microstructure (SEM). The paper presents interpretation results and determinates substrate’s grain size of raw materials dependence on the synthesis temperature.
