Ceramic Crucible Maximum Temperature

The crucibles are glazed on the inside and outside surface.

Ceramic crucible maximum temperature. Porcelain ceramic thermally shock resistant maximum temperature for use. A high quality porcelain crucible. The corundum ceramic crucible doesn t react with air water vapor hydrogen carbon monoxide so it is widely used in oxidizing and reducing atmosphere. Heating and cooling rates should not exceed 200 c per hour and maximum use temp of 1150 c.

B 26mm fits crucible 60103. The ability of a crucible to handle the rate of temperature change is as important as its minimum and maximum temperature limits.

When properly used the glazed pieces can withstand temperatures of 1050 degrees centigrade. 1750 c or 3180 f density. The unglazed porcelain rose style crucible eliminates the possibility of a reaction between the sample contents and a glazed coating. The porcelain is uniform in thickness and dense which allows stable mechanical strength and little permeability.

A crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. Catalog number capacity metric. The corundum crucible has the following advantages. The 99 alumina corundum ceramic crucible can work for long term under 1650 c and its maximum working temperature is 1800 c.
