Abstract
Inventia se refera la un procedeu de obtinere a unui produs refractar grafito-carborundic, prin presarea în matrite corespunzatoare a unui amestec constituit din grafit-fulgi, carbura de siliciu si adaosuri de sinterizare (alumina reactiva, siliciumetalic si argila refractara), amestecul fiind umectat, în prealabil, cu o solutie de dextrina, urmata de arderea produselor fasonate la o temperatura de maximum 1680 grade C.
