This material was produced in the Cabot corporation tantalum mine Manitoba for many years, but as of 2012 it is no longer available. One material being sold as a substitute is SC7.0 Spodumene from Talison Lithium in Australia (on paper its chemistry is almost identical to this material).

This is classified as minus 200 mesh concentrate. Although 10% is plus 200 mesh, all of this is minus 180 mesh. It was promoted by the company as single source of both alumina and silica and the analysis they provided only added up to 33 (the rest was assumed to be SiO2).
The company marketed the material to the steel industry as a casting powder and to the pyroceramics, glass, porcelain enamel, frit, glaze, abrasives, and waste vitrification industries.

They also had a standard 7.25% Li2O grade (1% on 48), a 6.8% Li2O grade (23% Al2O3, 55% passing 200 mesh) and a Spodulite grade (5% Li2O, 20% Al2O3).

The company also made a low-foam version that created fewer bubbles in ceramic slurries (a foaming process involving soap is used in the manufacture).
