#CMT# #/CMT# The paper mold has a layer (10) coming in contact with a material to be poured and made of fine pored, sintered ceramic material. The material has a porosity of 10x 10 power -1 meter to 30 micrometer, a porosity portion between 5 and 60 percent, and layer thickness greater than 2 millimeter. Another layer (11) arranged behind the layer (10) is made of a rough porous or foamed sintered ceramic material whose porosity is larger than the porosity of the fine pored layer (10). A temperature stable and heat conducting fabric (15) is introduced between the layers. #CMT#USE : #/CMT# Paper mold for pouring ceramic articles into a hollow or core mold for manufacturing a ceramic component, and for use as a press mold for manufacturing glass and plastic parts (all claimed). Uses include but are not limited to manufacture a pot, figurine, sanitary ware and architectural ceramic. #CMT#ADVANTAGE : #/CMT# The paper mold manufactures the ceramic component which is wastage free and porous and exhibits high abrasion resistance and durability. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a paper mold. 10, 11 : Layers 13, 14 : Vacuum sealed material 15 : Fabric #CMT#INORGANIC CHEMISTRY : #/CMT# The fine pored sintered ceramic material of the layer consists of corundum, mullite, zirconium dioxide, silicon carbide or silicon nitride. |
