- The possibilities of using an inorganic phosphate binder for the ablation casting technology are discussed in this paper. This kind of binder was selected for the process due to its inorganic character and water-solubility. Test castings were made in the sand mixture containing this binder. Each time during the pouring liquid alloy into the molds and solidification process of castings, the temperature in the mold was examined. Then the properties of the obtained castings were compared to the properties of the castings solidifying at ambient temperature in similar sand and metal molds. Post-process materials were also examined - quartz matrix and water. It has been demonstrated that ablation casting technology promotes refining of the microstructure, and thus upgrades the mechanical properties of castings (Rm was raised about approx. 20%). Properties of these castings are comparable to the castings poured in metal moulds. However, the post-process water does not meet the requirements of ecology, which significantly reduces the possibility of its cheap disposal.
