“…In non-ferrous smelting activities such as aluminum, copper, brass, gold, silver, and palladium, it is necessary to use quality crucible products. The choice of base material in the manufacture of crucibles must be appropriate to avoid contamination of the melt during smelting [14]. Table 1 shows the following refractory materials to high temperatures: The procedure for selecting crucible materials that have the potential to melt metals must consider several important aspects, namely the strength of the material from the interaction between the crucible and thermodynamics, such as melting temperature, softening, wettability, and resistance to thermal shock.…”

Industry in Indonesia continues to experience development in line with advances in science and technology, and this is because the industrial sector makes the most significant contribution to the national economy. However, industrial operations that are getting bigger can produce various kinds of waste, one of which is waste from the processing of plastic metallization applications and modern vacuum coating on food packaging, namely evaporation boats. The result of this waste is substantial because, in its application, evaporation boats will always be used as long as plastic food packaging continues to be produced around the world, so it is necessary to have handling for environmental sustainability in the future. Evaporation boat waste is waste that cannot be decomposed but can withstand heat and be used as a refractory material, especially as a primary material for making crucibles. This article presents a literature review focusing on the nature of evaporation boat waste and its effect on the mechanical and physical properties of the crucible material used in metal casting.

“…(ii) In interface interactions between the crucible and superalloy melt, the interface interactions include the physical dissolution of the crucible inner wall by the melt and the chemical dissolution of the crucible particle in the melt [17]. Previous research has shown that high-melting-point inclusions are introduced when using an Al 2 O 3 crucible to melt Ni-based superalloys [18,19]. (iii) Within the remelting parameters of Ni-based superalloys, the evidence presented thus far supports the idea that the vacuum level [20], smelting time [21], casting temperature [22], etc., can significantly affect the composition of the superalloy melt.…”

Oxide inclusions in Ni-based superalloys play a crucial role in determining their mechanical properties, oxidation resistance, and corrosion resistance at high temperatures. In this paper, the source and formation mechanism of different types of oxide inclusions in a high-aluminum Ni-based superalloy were systematically studied. An automatic field emission scanning electron microscope equipped with an energy dispersive spectrometer and a self-designed superalloy inclusion analysis standard was utilized to quantitatively reveal the oxide inclusion characteristics of the high-aluminum Ni-based superalloy prepared via vacuum induction melting (VIM) and vacuum induction remelting (VIR) processes. The experimental results indicate that the typical oxide inclusions in the Ni-based superalloy before the VIR process are irregular MgO·Al2O3 inclusions with sizes of less than 2 μm. After the VIR process, the typical oxide inclusions in the Ni-based superalloy are also MgO·Al2O3 inclusions. However, these oxide inclusions can be classified into three categories: (i) endogenous irregular MgO·Al2O3 inclusions, less than 4.3 μm in size, inherited from the master alloy; (ii) several hundred-micron film-like MgO·Al2O3 inclusions generated as interface reaction products between the MgO crucible and melts; and (iii) millimeter-scale MgO·Al2O3 inclusions and several tens of microns of MgO inclusions from the exfoliation of the MgO crucible matrix.
