“…Binders are required for the production of crucibles in order to hold the raw materials together during the manufacturing process and provide the necessary strength and durability [20]. Clay, oxidation-resistant materials, hybrid binders, carbon binders, liquid coal tar, and kaolin clays are commonly used as binders for crucible manufacturing, especially graphite crucibles [21]− [25]. Molasses is produced as a byproduct of sugar refining.…”

Crucibles are critical equipment utilized across numerous industries, and they are notably costly. In this study, the influence of molasses concentrations on the properties of crucibles fabricated from evaporation boat waste products is explored. The evaporation boat waste was powdered and filtered using a 100 mesh sieve. The molasses concentrations added during the mixing procedure were as follows: 0%, 5%, 10%, 15%, and 20% by weight. After 120 minutes, the mixture was compacted using 25 MPa pressure. The green body formed was dried at 100 ̊C for 300 minutes and fired at 1150 ̊C for 240 minutes. The obtained specimens were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), density testing, hardness testing, and flexural testing. The results of this study demonstrate that the addition of molasses has significant effects on the properties of the crucibles. Specimens using molasses with a concentration of 5 wt% produce better physical and mechanical properties than other specimens. The density, hardness, flexural strength, and weight percentages of Boron nitride (BN) and Titanium diboride (TiB2) phases in the specimen with 5 wt% molasses were 2.36 g/cm3, 64 HRA, 31.5 MPa, 68.9%, and 31.1%, respectively. The use of evaporation vessel waste and molasses in the production of crucibles in this study is in line with Sustainable Development Goals (SDGs) 3, 7, 14, and 15, which relate to improving excellent health and well-being, ensuring access to affordable energy, and conserving marine and terrestrial ecosystems.

The main criteria for evaluation of ceramic products’ properties are strength, structural and mechanical, and thermophysical properties. To produce ceramic composites with a wide range of structural, mechanical, strength, and performance properties depending on application, various additives (flux agents, sintering agents, fillers) and heat treatment processes are used. Studies to determine a rational mixture composition have been carried out. A multipurpose material, comprising particles of the basic chamotte filler (burned clay) with a bonding agent in the form of refractory clay from the Latnenskoye deposit with a field spar fluxing agent, an additional filler made of heat-resistant silicon carbide, and an adhesive component in the form of powdered dextrin, is suggested. According to the combination of its ensured parameters, the obtained ceramic material can be multipurpose. Its degree of porosity and permeability make the material filtering, sound-proofing, and heat-retaining; considering the low density, it can be used as a lightweight construction material.
