The specific heat capacity of ceramic sand is 2210J / ( kg · K ). In addition, the Al2O3 content of the ceramic sand is generally more than 70 %, and its pH value is about 7.6.It is a neutral material with a refractoriness of ≥ 1800 °C and a bulk density of 1.95 ~ 2.05g / cm3.It is only 0.73 ~ 0.74 times that of the chromite sand, and the shape is spherical or nearly spherical, the specific surface area is small, and the angular coefficient is ≤ 1.1.At room temperature, the compressive strength is 46MPa, the thermal conductivity is 0.5 ~ 0.6W / ( m · k ), and the thermal expansion rate is 0.03 % ~ 0.13 %.
