  • Patent number: 10815155
    Abstract: To provide a high-zirconia electrocast refractory in which occurrence of cracks in manufacture and occurrence of cracks in use as a furnace material is further reduced while maintaining extremely high corrosion resistance to molten glass. The high-zirconia electrocast refractory contains 96.7 to 98.5 mass % of ZrO2, 0.8 to 2.7 mass % of SiO2, 0 to 0.2 mass % of Na2O, 0.21 to 1 mass % of K2O, 0.1 to 0.4 mass % of Al2O3, and does not substantially contain B2O3, in terms of oxide, as a chemical composition, wherein contents of the Na2O and the K2O satisfy a relation of following Formula (1) 0.15 mass %?CK2O/2+CNa2O?0.6 mass %??(1) where CK2O is the content of K2O and CNa2O is the content of Na2O, and each of the contents is expressed by mass % in the refractory.

  • Patent number: 4325629
    Abstract: Image forming methods and apparatus for forming an image, using an image forming sheet which has on an organic substrate to heat-developable image forming layer that is normally non-photosensitive but is rendered photosensitive by preheating prior to exposure and forms therein a latent image by exposure and then provides a visible image by heat development. An image forming area of the image forming sheet is preheated and heat-developed to obtain the visible image.
