ZIRCONIUM-BASE SINTERED PRODUCT

摘要

The inventive sintered product is produced from an initial feedstock having a zirconium content ranging from 75 to 99 % and the following average chemical weight composition, in percentage by weight, based on oxides: 60 % = ZrO<SUB>2</SUB>+ HfO<SUB>2</SUB>= 75 %, 27 % = SiO<SUB>2</SUB> = 34 %, 0,2 = TiO<SUB>2</SUB>= 1,5 %, 0,3 < Y<SUB>2</SUB>O<SUB>3</SUB>= 3,5 %, other oxides: = 1 %, to give a total of 100 %. Said product can be used for glassworks.
