Abstract
1629. Lewes, V. B. Jan. 22. Mantles containing alumina and chromic oxide, with or without zirconia and thoria, are prevented from shrinking and buckling by adapting them for use on inverted burners. The compositions preferred are : 87 parts of alumina, 4 parts of zirconia, and 9 parts of chromic oxide ; 48 to 60 parts of alumina, 42 to 35 parts of thoria, and 5 to 10 parts of chromic oxide.
