Summary 1. The comparative effect of various packings and gaseous atmospheres on the heating of sintered articles was studied. 2. A substantial effect of the atmosphere on the heating time of sintered articles was shown; other conditions being equal, minimal holding times are needed during sintering in hydrogen and maximal during sintering in argon and nitrogen. This must be taken into account when establishing the sintering regimes in different atmospheres. Other conditions being equal, the duration of sintering (heating + holding at a given temperature) in an atmosphere of argon, nitrogen, and air should be about 1–1.5 h longer than in an atmosphere of hydrogen and helium. 3. Experimental nomograms were constructed for determining the heating time of sintered articles under a packing layer of known thickness with uni- and bilateral heating in a furnace with a constant temperature.
