  • Patent number: 4129680
    Abstract: A process is disclosed for producing chrome alloys in a form suitable for casting dental appliances. A chrome dental alloy which is inherently capable of being processed, prior to casting the appliance, to wrought form by hot working is first fused to form a melt in a heating means (e.g., an electron beam hearth) which substantially excludes the presence of or substantially removes tramp elements (e.g., carbon, oxygen and nitrogen). The melt is then cast into an ingot which is subsequently hot-worked to form a shaped piece (e.g. bar, strip, rod or wire). The shaped piece is next cut into small weight pieces of predetermined size convenient for handling by dental laboratories and the pieces are coated with water glass (e.g., sodium silicate) so as to protect the pieces from contamination with tramp elements during the heating period preparatory to melting and casting into dental appliances.
