Date Jan. 16, 1997A method and powder mixture are described for cutting a refractory body. The powder mixture comprises refractory metal oxide particles and fuel particles which burn exothermically by combining with oxygen to form a refractory oxide. The mixture is characterised in that the refractory metal oxide of the powder mixture comprises calcium oxide and/or magnesium oxide. The powder mixture enables refractory bodies to be cut more effectively than hitherto. |
