    Since nothing about the composition is given and based on appearance only, I suspect they are the same.

    You might find the definition of cement from Wikipedia interesting and perhaps related:

    Thus, the shell is probably a ceramic and the potting material used to secure the resistance element may correctly be called a cement. I see no reason the potting element could not also be a low-temperature ceramic.

    Did you perhaps mean cermet- ceramic-metal resistor?

    No, some market resistors as "cement", wondering if these are same as ceramic though.

    All the examples you refer to are high wattage wire-wound resistors in a ceramic/cement body. For all practical purposes they are all identical and whether they are called cement or ceramic seems to depend on the whim of the manufacturer/supplier.
