This invention provides a composition and a process for forming sintered, molded articles having improved dimensional stability. More particularly, this invention pertains to a composition having a sugar additive that increases the solids loading potential of the composition and a process for forming injection molded articles therefrom. Increasing the solids loading potential of the composition, enables the formation of metal or ceramic articles attaining about 98-99 % of their theoretical maximum density, without cracking or shrinking significantly during sintering.
L'invention concerne une composition et un procédé de formage d'articles frittés et moulés présentant une stabilité dimensionnelle améliorée. Plus précisément, l'invention concerne une composition possédant un additif de sucre qui accroît le potentiel de charge des matières solides de la composition et un procédé de formage d'articles moulés par injection à partir de cette composition. Le fait d'accroître le potentiel de charge des matières solides de la composition permet la formation d'articles métalliques ou céramiques atteignant environ 98-99 % de leur densité maximum théorique, sans fissure ou retrait signifiants pendant le frittage.
