Pra\u0161ak silicijskog karbida je tako\u0111er poznat kao emery, proizvodi su \u0161esterokutni kristali, specifi\u010dna te\u017eina 3,20\u20133,25, tvrdo\u0107a po Mohsu 9,2, mikrotvrdo\u0107a 2840\u20133320 kg\/mm2. Silicijski karbid ima stabilna hemijska svojstva, visoku toplotnu provodljivost, mali koeficijent toplotnog \u0161irenja i dobru otpornost na habanje.Pra\u0161ak silicijskog karbida ima mnoga glavna podru\u010dja primjene, kao \u0161to su funkcionalna keramika, strukturna keramika, napredni refraktori, abrazivi i metalurgija i tako dalje.<\/p>\n

(1) Abarzivno<\/p>\n

Pra\u0161ak silicij-karbida se mo\u017ee koristiti kao abrazivno sredstvo ili pomo\u0107ni materijal za bru\u0161enje i obradu stakla, kvarcnog kristala, prizmati\u010dnog kristala, keramike, kamena, lijevanog \u017eeljeza i nekih obojenih metala, cementiranog karbida, titanijumskih legura, brusnih kota\u010da za rezne alate od brzorecepnog \u010delika i sli\u010dno.<\/p>\n

(2) Metalur\u0161ki i visokotemperaturni refraktivi<\/p>\n

Primjene u \u010deli\u010danim pogonima: deoksidator od silicij-karbida i pjenasti kerami\u010dki filteri; filteri od silicij-karbida i pjenaste keramike, s izvrsnom \u010dvrsto\u0107om, otporno\u0161\u0107u na udar visokih temperatura i hemijsku koroziju. Radna temperatura iznad 1380 \u00b0C; \u0161iroko se koriste za filtraciju rastopljenog metala, obradu dimnih gasova na visokim temperaturama, kao nosa\u010di katalizatora, u \u010dvrstim izmjenjiva\u010dima topline, za posebna punila i u drugim podru\u010djima.<\/p>\n

(3) Strukturni\/funkcionalni kerami\u010dki materijali (reakcijsko sinteriranje\/sinteriranje bez pritiska)<\/p>\n

Idealan materijal za izradu silicij-karbida, poput otpornih na habanje cijevi, radilica, komora pumpi, ciklona, obloga korpe za rudu, s otporno\u0161\u0107u na habanje i vijekom trajanja 5\u201320 puta ve\u0107im od lijevanog \u017eeljeza ili gume, a tako\u0111er jedan od idealnih materijala za zra\u010dne piste. Bespritisno sinterirani silicij-karbid mo\u017ee se koristiti za kerami\u010dke plo\u010de otporne na metke, kerami\u010dke listove i kerami\u010dke umetke.<\/p>\n
