Abstract
POSTUPAK ZA PROIZVODNJU KALUPOM OBLIKOVANOG SAMONOSECEG KERAMICKOG TELA, naznacen time, sto se: (a) priprema oblikovani osnovni metal koji ima deo modela; (b) nanosi na deo modela prilagodljiv, za gas propusan materijal da se pripremi kalup koji ima oblikovanu povrsinu koja je u sustini podudarna sa delom modela, pri cemu je materijal sustinski samovezujuci bar u nosecoj zoni istoga neposredno blizu povrsini i koji se prostire u istom pravcu sa povrsinom, da se pripremi kalup sa dovoljno kohezione cvrstoce da sadrzi celovitost oblikovane povrsine pod procesnim uslovima koji se definisu u sledecim fazama (d) i (e); (c) odredjuje polozaj osnovnog metala i suda da se osnovni metal stavi u protocnoj vezi sa prihvatnim sudom, pri cemu je zapremina prihvatnog suda dovoljna da bar u sustini primi sav osnovni metal u tecnom obliku; (d) zagreva osnovni metal do temperaturnog podrucja iznad njegove tacke topljenja ali ispod tacke topljenja njegovog proizoda reakcije oksidovanja i dobijeni stopljeni metal prazni iz kalupa u prihvatni sud da se pripremi supljina kalupa; (e) nastavlja zagrevanje u prisustvu oksidansa u parnoj fazi i, u tom temperaturnom podrucju; (I) reaguje stopljeni osnovni metal sa oksidansom da se nagradi proizvod reakcije oksidovanja, (II) odrzava bar deo proizvoda reakcije oksidovanja u dodiru sa i izmedju tela stopljenog metala i oksidansa, da se metal potpuno izvuce iz tela kroz proizvod reakcije oksidovanja i u kalup za dodir sa oksidansom tako da proizvod reakcije oksidovanja nastavlja da se stvara unutar kalupa na medjupovrsini izmedju oksidansa i prethodno stvorenog proiz-voda reakcije oksidovanja; (III) nastavlja reakcija da nastaje proizvod reakcije oksidovanja u dodiru sa oblikovanom povrsinom, stvarajuci pri tom keramicko telo ciji je oblik odredjen oblikom supljine kalupa; i (f) vadi se keramicko telo iz kalupa.
