He hiʻohiʻona o nā diski graphite

Loaʻa ka SIC i uhi ʻia i ka pōhaku wili i nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻana o ka oxidation, ka maʻemaʻe kiʻekiʻe, ka waikawa, ka alkali, ka paʻakai a me nā mea hoʻonaninani kūlohelohe, a me ka hana kino a me ka hana kemika. Ke hoʻohālikelike ʻia me ka graphite maʻemaʻe kiʻekiʻe, ka graphite maʻemaʻe kiʻekiʻe ma 400 ℃ e hoʻomaka ana i ka oxidation ikaika, ʻoiai inā ʻaʻole kiʻekiʻe ka mahana, ʻo ka noi lōʻihi ma muli o ka oxidation a me ka pauka, e hilinaʻi ana i ka mea hana a me ka papaʻaina a i ʻole ka pollution o ka hoʻohana ʻana i ke kaiapuni. , No laila, ʻo ka SIC coating graphite base e like me kahi mea hana MOCVD hou, ke kaʻina hana sintering pauka e hoʻololi mālie i ka graphite maʻemaʻe kiʻekiʻe.

Nā hiʻohiʻona nui:

1. ʻO ka antioxidant wela kiʻekiʻe: antioxidant, ʻoi aku ka maikaʻi o ka hana antioxidant ke piʻi ka mahana e like me 1600 ℃;

2. Maʻemaʻe kiʻekiʻe: loaʻa ma ke ʻano o ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe;

3. Erosion kū'ē: kiʻekiʻe paʻakikī, ili paʻapū, nā ʻāpana maikaʻi;

ʻO ka pale ʻana i ka corrosion: acid, alkali, paʻakai a me nā reagents organik;

5. ʻO ka papa ʻili SIC he β-silicon carbide, he cubic i hoʻonohonoho ʻia i ka maka.
