The unglazed porcelain rose style crucible eliminates the possibility of a reaction between the sample contents and a glazed coating.
Ceramic crucible maximum temperature.
The ability of a crucible to handle the rate of temperature change is as important as its minimum and maximum temperature limits.
A crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures.
Heating and cooling rates should not exceed 200 c per hour and maximum use temp of 1150 c.
The 99 alumina corundum ceramic crucible can work for long term under 1650 c and its maximum working temperature is 1800 c.
Ultra high temperature ceramics uhtcs are a class of refractory ceramics that offer excellent stability at temperatures exceeding 2000 c being investigated as possible thermal protection system tps materials coatings for materials subjected to high temperatures and bulk materials for heating elements.
If your operational practices lead to frequent heating and cooling cycles for the crucible or otherwise subject it to rapid temperature changes you will need to select a crucible that is resistant to thermal shock.
A high quality porcelain crucible.
The corundum crucible has the following advantages.
The porcelain is uniform in thickness and dense which allows stable mechanical strength and little permeability.
