| titleOfInvention | A composition for molding silica sleeve and a method of preparing silica sleeve therefrom |
| abstract | The present invention provides a composition for forming a siliceous sleeve comprising a fused silica powder and an ultrafine fumed silica powder of granulation, a basic aqueous solution, polyethyleneimine (PEI) and a pH reducing agent as a dispersant, and a method for producing a siliceous sleeve therefrom. do. The method for producing a siliceous sleeve of the present invention comprises the steps of dispersing ultrafine fumed silica powder in water in a fused silica powder of granulation to prepare a water-based silica slurry; Adding a basic aqueous solution to the slurry to increase the pH of the slurry to 10 or more and redispersing; Adding polyethyleneimine (PEI) and a pH reducing agent to the redispersed slurry to mix uniformly; Pouring the slurry into a mold of a desired shape to gelate the slurry; And drying the gelled molded body, followed by calcination and firing. |
