What kind of crucible is suitable for the synthesis of cement; if the compacted pallet is being transformed into a liquid, at a temperature of 1500 deg C?
You need special platinum crucibles: Platinum-Rhodium, fine-grain stabilized. A reinforced rim is also helpful as you need to quench the burned clinker in air. This means that you need to remove the crucible from the oven using crucible tongs. A reinforced rim is more durable.
From my best knowledge, platinum vessels are the best option, however, very expensive.

Platinum crucibles are the best for this purpose.
Trying alumina crucible can help (reduce the cost) but they will break as they cannot resist the temperature shock during quenching.
Platinum crucibles are the best. Alumina crucibles are not suitable for quenching they can't resist thermal shocks (you may see the formation of cracks in the crucible even if you do quenching in the air). Also, at high temperatures, some of the melting material may dissolve into the crucible and become part of it. Graphite crucibles usually contaminate the sample (you may see some of the black materials with the final powder).
Dear Dr. Rajesh Kumar Sharma,
You have started a very interesting issue to be discussed which reads as follows: What kind of crucible is suitable for synthesis of cement; if the pallet is being transformed into liquid at temperature of 1500 deg C ? IO can't make any contribution on this issue but I will follow the discussion and I will make comments based on my understanding of the subject created or achieved from the discussion.
Best Regards
