Crucible chemistry - High Temperature Crucibles at Thomas Scientific

They are particularly suitable when precipitates will not be dried at temperatures above 110°C and may be used at higher temperatures.

Active ingredients, which help with spreading or destabilizing foam, can include waxes, metal salts, silicas or other hydrophobic particles.

Allow it to cool for a few minutes and then place it in the desiccator.

Allowing a metal bath to be held at a minimal temperature for a lengthy period of time will accelerate crucible oxidation.

Resistance Furnace: Electric resistance furnaces provide even, all round heating to a graphite crucible and are ideally suited for even and precise temperature control in metal holding application.

By the late Medieval period steel production had moved from India to modern-day Uzbekistan where new materials were being used in the production of steel crucibles, for example Mullite crucibles were introduced.
