Ibisobanuro bigufi

Alumina y'umukara ikorwa no gushonga kwa Calcined Bauxite mu itanura ry'amashanyarazi ku bushyuhe burenze 2000°C. Uburyo bwo gushonga buhoro buhoro bukurikira ivangavanga, kugira ngo haboneke kristu zifunganye. Gushonga bifasha mu gukuraho sulfure na karubone bisigaye, kugenzura neza urugero rwa Titania mu gihe cyo guhuza ibinyampeke bituma ibinyampeke bikomera neza.

Hanyuma ifu ikonje irasenywa, isukurwamo imyanda ya rukuruzi mu byuma bitandukanya rukuruzi bikomeye kandi bigashyirwa mu byiciro bito kugira ngo bijyane n'ikoreshwa rya nyuma. Imirongo yihariye ikora ibicuruzwa bikoreshwa mu buryo butandukanye.

Porogaramu

Alumina y'umukara ivanze n'icyuma gityaye kandi gikarishye, gikwiriye cyane gusya ibyuma bifite imbaraga nyinshi zo gukurura. Imiterere yayo y'ubushyuhe ituma iba ibikoresho byiza cyane byo gukoresha mu gukora ibintu birwanya ubushyuhe. Iki gikoresho gikoreshwa no mu bindi bikorwa nko guturika no gukomera kw'ubuso.
