Ceramic Crucibles

Tecnoserv offers Ceramic Crucibles. These are a special product for the special glass and super metal industry made by plasma sputtering technology. The material is 99.9% Al2O3. These crucibles have a high thermal shock resistance and they are super strong based on advanced ceramic technology. Plasma sputtering technology provides the following performance: resistance to thermal shock, controlled porosity, gas tightness, stability and precision of the ceramic body without additional processing, high temperature resistance to aluminium slags. It is also possible to combine platinum crucibles with plasma sputtering technology. This composite crucible allows the manufacturer to realize a lower consumption of platinum up to 80%: here you can limit the thickness of the platinum layer to approx. 0.3 mm. Applications of these plasma sputtered crucibles are: as crucible for melting of all metals and alloys without reaction with the crucible material and fusing temperature up to 1,900°C and for special glass industries up to 1,550°C; as funnel, chute, lids and other elements of melting-pouring units (lack of oxidant impregnations in melts are guaranteed); bushing in graphite crucible for melts defence of carburisation; crucibles for casting of jewellers and dental alloys based on Co, Ni, Cr; and as thermal screen and thermo containers in vacuum furnaces and open induction heating. Available in maximum wall thickness of 15 mm; maximum diameter of 400 mm and maximum height of 1250 mm and crucible volume from 0.1 - 100 ltr.
