## Description

- description: In this study, thermal analysis (including differential thermal analysis
    and thermogravimetric analysis coupled with mass spectrometry) was used to design
    the sintering process of alumina as well as Al2O3–Mo and Al2O3–Ni green bodies
    obtained by digital light processing (DLP) 3D printing. The measurements were
    performed for selected organic additives, which are commonly used in the DLP technique,
    such as photoinitiators, dispersing agents, and organic monomers. Additionally,
    metallic powders (Ni, Mo), as well as ceramic and composite green bodies, have
    been subjected to thermal analysis. The obtained results allowed us to determine
    proper sintering conditions for a two-step sintering program. Firstly, the organic
    phase was burnt out at 400 °C in the air. At this temperature, metallic powders
    have not yet started to oxidize, and most of the organic additives have already
    been eliminated from the sample. The second step was performed using spark plasma
    sintering at 1150 °C with a pressure equaling 60 MPa in an argon atmosphere to
    prevent the oxidation of metals. The samples were gradually cooled down to 800
    °C at a cooling rate of 35 °C min−1 and then furnace-cooled to room temperature,
    preventing the formation of intrinsic defects (microcracks) in a multicomponent
    ceramic–metal composite. The XRD and SEM–EDS analysis allowed us to conclude that
    the obtained composites are well densified, no other phases apart from alumina
    and metals are present in the samples, and that the alumina grain growth is smaller
    than for conventional sintering. An increase in fracture toughness for the composite
    samples was observed compared to pure alumina. https://doi.org/10.1007/s10973-025-14596-9
