From my experience, stove cement and furnace cement are the same or very similar,, it comes in a can or tube, is used like putty or slightly adhesive putty, and is very difficult to get off your fingers and out of clothing.. The putty is used to seal joints, flue pipes, or repair small gaps or non-structural cracks..
Refractory cement is more like mortar or concrete, but is a mix that is meant to be molded or poured in or around a firepot, or to make curved 'firebrick' or in one way or another be used in a firebox and have fire on or against it..
If I'm wrong on the above descriptions,, the forum readership will correct me..

The two things I have on hand are "Furnace and Retort Cement" and "Insulall" furnace cement. The Furnace and Retort Cement is pre-mixed and is used to cement the burner head onto the air chamber. I think that's refractory - withstands very high heat, heat cured, and very smooth. The Insulall is insulating cement for boilers, flues, ductwork, etc. It is dry and looks like it has oatmeal added to it. For best results, it needs about 10% Portland added to it or it will take forever to cure, is somewhat soft, and shrinks quite a bit. Both say furnace cement, so it's a little confusing.
