Semiconductor silicon nitride ceramics

ʻO ka wehewehe pōkole:

ʻOi aku ka maikaʻi o ka pale ʻana i ka haʻalulu wela ma mua o nā seramika ʻē aʻe. Hoʻohui pū ʻia me ka ikaika kiʻekiʻe, ka hoʻonui haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion maikaʻi a me ka paʻakikī o ka haki, hoʻohana pinepine ʻia ka silicon nitride i ka aerospace a i ʻole nā ʻoihana kaʻa. ʻO nā noi ʻē aʻe e like me nā nozzles kuni, ka hoʻoheheʻe ʻana i ka metala, a me nā mea ʻē aʻe. umekaumaha.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

ʻO ka silikoni nitride ka mea hina hina me ka paʻakikī haʻihaʻi kiʻekiʻe, maikaʻi loa ka pale ʻana i ka haʻalulu wela, a me nā waiwai hiki ʻole ke hiki ke hoʻoheheʻe ʻia.

Ke hoʻohana nei i kēia mau hiʻohiʻona, ua hoʻopili ʻia i nā ʻāpana ʻenekini hoʻopau i loko e like me nā ʻāpana mīkini kaʻa, nā nozzles blowpipe mīkini welding, etc.

Me kona pale ʻaʻahu kiʻekiʻe a me ka ikaika mechanical kiʻekiʻe, e hoʻonui mau ana kāna mau noi i ka lawe ʻana i nā ʻāpana roller, rotating shaft bearings a me nā ʻāpana hana semiconductor.

Nā waiwai o nā seramika nitride silika

1, loaʻa ka ikaika kiʻekiʻe i kahi pae wela nui;

2, kiʻekiʻe haʻi paʻakikī;

3, ikaika kulou maikai;

4, kū'ē i ka luhi mechanical a me ka kolo;

5, māmā - haʻahaʻa haʻahaʻa;

6, kiʻekiʻe paʻakikī a ʻaʻahu kūʻē;

7, maikaʻi loa thermal haʻalulu kū'ē;

8, hoʻonui wela haʻahaʻa;

9, insulator uila;

10, maikaʻi oxidation kū'ē;

11, maikaʻi kemika corrosion kū'ē.

He haʻahaʻa haʻahaʻa ka hoʻonui ʻana o ka wela a me ka conductivity thermal kiʻekiʻe, no laila, loaʻa iā lākou ke kūpaʻa haʻalulu wela. ʻAʻole e haki ka nitride silicon sintered wela ma hope o ka wela ʻana i 1000 ℃ a hoʻokomo i loko o ka wai anuanu. ʻAʻole kiʻekiʻe loa ka mahana, silicon nitride ka ikaika kiʻekiʻe a me ka hopena o ka hopena, akā ma luna o 1200 ℃ e hōʻino ʻia me ka ulu ʻana o ka manawa hoʻohana, i hoʻemi ʻia kona ikaika, ʻoi aku ka nui o ka pōʻino luhi ma luna o 1450 ℃, no laila ka hoʻohana ʻana. ʻAʻole ʻoi aku ka nui o ka mahana o Si3N4 ma mua o 1300 ℃.
