    摘要: A heat-resistant material for a low-melting metal casting machine is provided to have improved durability against highly-corrosive molten metal while maintaining excellent thermal-insulation characteristics, specific strength, and processability of calcium silicate. A heat-resistant material for a low-melting metal casting machine includes calcium silicate and a fluorinated compound. The fluorinated compound is contained in an amount of 0.05-30wt% in terms of a fluorine content. The calcium silicate comprises at least one element selected from the group consisting of wallastonite(CaSiO3), tobermorite(5CaO.6SiO2.5H2O), and xonotlite(6CaO.6SiO2.H2O). The heat-resistant material has a density of 200-2,500 kg/m^3 and a bending strength of 1-20 MPa.
