    Abstract: PROBLEM TO BE SOLVED: To provide a process for easily determining the hardness of an extremely thin coating layer applied to a sintered ceramic material having arbitrary surface roughness with a non-destructive method in high accuracy and provide a sintered ceramic material coated with a coating layer composed of an inorganic component and having a hardness suitable for magnetic head slider and machine tool and produced by the quality control to specify the hardness of the coating layer composed of the inorganic component by using the above determination method.
    SOLUTION: This sintered ceramic material 1 having an extremely thin coating layer composed of an inorganic component and having a hardness of 400-620 kgf/mm
    2 is produced by specifying the hardness of the coating layer 2 composed of an inorganic component, having unknown hardness and formed on the surface of a sintered ceramic material by a non-destructive method based on the relationship between the hardness and the density determined by using standard specimens.

    Abstract: PURPOSE: A mortar composition with an improved heat storing performance by including a phase change material is provided to reduce energy consumption and carbon dioxide by adjusting the mixing amount and the melting point of a paraffin-based phase change material. CONSTITUTION: A mortar composition includes cement, sand, water, and paraffin-based phase change material. The paraffin-based phase change material is a C13 to C24 paraffin-based material. The melting point of the paraffin-based phase change material is between 23 and 32 degrees Celsius. The density, the thermal conductivity, the heat storing capacity, and the specific heat capacity of the paraffin-based phase change material are between 0.6 and 0.75 kg/l, between 4 and 4.5 kcal/hm°C, between 110 and 180 kJ/kg, and between 1.0 and 2.0 kJ/(KgxK). A method for manufacturing the mortar composition includes the paraffin-based phase change material and cement mixing process and a sand and water introducing process with respect to the mixture.
