Abstract
2994. Karyscheff, A. A. de. Feb. 6. Fire-bricks. - A mixture for making bricks of artificial spinels comprises aluminates 102 parts, magnesites 40, agglutinant 16, boracic acid 3, naphtha residue 2, water containing boric oxide 5, and sometimes 0À2 per cent of fluoride. The brick is moulded under high pressure, slowly dried, and burnt at a temperature of over 2400‹ C. The brick may be used directly or may be powdered and used as the artificial spinel constituent of mixtures such as that subsequently described. The following is an example of the proportions used for making a refractory cement, namely : natural spinel, powdered 35 parts, crushed 12 ; artificial spinel, powdered 78, and crushed 70; agglutinant 16 ; boracic acid 0À35; naphtha residue 1 ; boiling water 6 ; calcium fluoride 0À50; lampblack 0.15. When the cement is used for lining furnaces, 5 per cent of iron protoxide is added and 2À5 to 3 per cent of zinc oxide, and the quantity of boracic acid is increased. Hollow articles and bricks are made from somewhat similar compositions.
