Pulberea de carbur\u0103 de siliciu este, de asemenea, cunoscut\u0103 sub numele de emery, produsele sunt cristale hexagonale, greutate specific\u0103 3.20-3.25, duritate Mohs 9.2, microduritate 2840-3320kg\/mm2. carbura de siliciu are propriet\u0103\u021bi de propriet\u0103\u021bi chimice stabile, conductivitate termic\u0103 ridicat\u0103, coeficient mic de dilatare termic\u0103 \u0219i rezisten\u021b\u0103 bun\u0103 la abraziune. pulberea de carbur\u0103 de siliciu are multe domenii majore de aplicare, cum ar fi ceramica func\u021bional\u0103, ceramica structural\u0103, refractare avansate, abrazive \u0219i metalurgice \u0219i a\u0219a mai departe.<\/p>\n

(1) Abraziv<\/p>\n

pulberea de carbur\u0103 de siliciu poate fi utilizat\u0103 ca material de m\u0103cinare sau material auxiliar de m\u0103cinare pentru m\u0103cinarea \u0219i prelucrarea sticlei, cristalului de cuar\u021b, cristalului prismat, ceramicii, pietrei, fontei \u0219i a unor metale neferoase, carbur\u0103 cimentat\u0103, aliaje de titan, discuri de m\u0103cinare pentru scule de t\u0103iere din o\u021bel de mare vitez\u0103 \u0219i a\u0219a mai departe.<\/p>\n

(2) Materiale refractare metalurgice \u0219i pentru temperaturi ridicate<\/p>\n

Aplica\u021bii de o\u021bel\u0103rie ale deoxidantului de carbur\u0103 de siliciu \u0219i filtre ceramice din spum\u0103, filtre ceramice din spum\u0103 de carbur\u0103 de siliciu, cu o rezisten\u021b\u0103 excelent\u0103 \u0219i rezisten\u021b\u0103 la impactul la temperaturi ridicate \u0219i rezisten\u021b\u0103 chimic\u0103 la coroziune. temperatur\u0103 de utilizare peste 1380 de grade Celsius, utilizate pe scar\u0103 larg\u0103 \u00een filtrarea metalelor topite, tratarea gazelor de ardere la temperaturi ridicate, purt\u0103tori de catalizatori, schimb\u0103toare de c\u0103ldur\u0103 solide \u0219i umpluturi speciale \u0219i alte domenii.<\/p>\n
