| abstract |
The present invention provides a reaction mixture, a gel composition that is a polymerization product of the reaction mixture, a shaped gel article that is formed within a mold cavity and that retains the size and shape of the mold cavity when removed from the mold cavity , and a sintered article prepared from the shaped gel article. The sintered article has the same shape as the mold cavity (except for the regions where the mold cavity is overfilled) and the shaped article, but is reduced in size in proportion to the amount of isotropic shrinkage. The present invention also provides a method of forming the sintered article. |
