Ua ʻike nui ʻia ka pauka micro Silicon carbide (SiC) ma ke ʻano he mea hoʻolālā koʻikoʻi ma waena o ka hana ʻenehana kiʻekiʻe, nā ʻōnaehana ikehu, a me nā keramika holomua. Me ka paʻakikī koʻikoʻi, ka conductivity thermal, ke kūpaʻa kemika, a me ke kūpaʻa ʻana i ka ʻaʻahu, kākoʻo ka micropowder SiC i ka hoʻopau pololei, nā kaʻina hana semiconductor, a me nā ʻāpana uila a me ka thermal o ka hanauna e hiki mai ana.

He aha ka Silicon Carbide Micropowder? — Nā Waiwai Koʻikoʻi

Pauka microcarbide siliconnā hiʻohiʻona:

• Paʻakikī Mohs kiʻekiʻe (>9)

• Nā ʻano semiconductor bandgap ākea

• Ka hoʻokele wela kiʻekiʻe

• ʻOi aku ka maikaʻi o ka pale ʻana i ka pala a me ka oxidation

• Ka moakāka infrared a me ke kūpaʻa optical

• Hoʻonui wela haʻahaʻa

• Ka inertness kemika

ʻO kēia mau ʻano i hui pū ʻia e hoʻolilo iā SiC i mea multifunctional kūpono no nā noi abrasive a me nā hana.

1. Nā noi hoʻopau ʻili a me ka pololei

I ka wā ma mua, ʻo ka ʻāpana mākeke nui loa no ka silicon carbide micropowder ka hana abrasive. Hāʻawi ʻo SiC i nā ʻaoʻao ʻoi aku ka ʻoi a me nā wikiwiki o ka wehe ʻana i nā mea i hoʻohālikelike ʻia me nā alumina abrasives.

ʻO nā hoʻohana koʻikoʻi:

• Ke wili ʻana a me ka ʻoki ʻana i nā mea paʻakikī

• Ka hoʻowali ʻana i ka ʻōlinolino (aniani, sapeiro, aniani)

• Hoʻopau ʻana i ka hoʻoheheʻe metala

• Hoʻolālā wafer semiconductor

• Hoʻopau ʻana i ke aniani a me ka prism

Hiki i ka SiC micropowder ke hoʻopau i ka ʻili pālahalaha me ka hemahema haʻahaʻa, he mea koʻikoʻi ia no nā optics holomua a me nā substrates semiconductor.

2. Nā noi Semiconductor a me nā mea uila

Ua hoʻolalelale ka hoʻololi ʻana o ka semiconductor i nā mea ākea-bandgap i ke koi nopauka liʻiliʻi SiCI loko o nā mea uila mana, ʻoi aku ka maikaʻi o nā hāmeʻa SiC ma mua o ka silicon ma nā wahi voltage kiʻekiʻe, alapine kiʻekiʻe, a me nā mahana kiʻekiʻe.

ʻO nā noi pili e pili ana i kēia mau mea:

• ʻO ka hoʻopili ʻana i ka wafer / CMP slurries

• Ka hoʻomākaukau ʻana o ka substrate wafer SiC

• ʻO ka hoʻopili ʻana o ka dielectric a me ka seramika

• Nā mea hoʻolaha wela wela no nā ʻāpana mana kiʻekiʻe

ʻO nā kaʻa uila (EV), nā photovoltaics (PV), nā kikowaena ʻikepili, a me nā ʻoihana 5G nā mea hoʻokele ulu nui no nā mea e pili ana i ka SiC.

3. Nā keramika holomua a me nā mea paʻa ʻole

Hana ka SiC micropowder ma ke ʻano he pae hoʻoikaika i nā ʻano hana seramika hana kiʻekiʻe mahalo i kona ikaika a me ke kūpaʻa wela.

ʻO nā mākeke maʻamau:

• Nā lako a me nā ipu hoʻoheheʻe umu

• Nā ʻōmole puhi

• Nā ʻāpana pale ʻaʻahu

• Nā ʻāpana Turbine a me nā ʻāpana aerospace

• Nā ʻāpana bearings a me ka pamu

Pono nā ʻoihana e like me ka metallurgy, aerospace, a me ka ikehu i nā mea e mālama i ka ikaika ma luna o 1400°C a kūʻē i ka ʻinoʻino kemika—nā waiwai i kūlike loa me nā keramika SiC.

4. Nā Hana Mālama Pākahi, Kelepona Wahie a me ka Ikehu

Ke hoʻokumu nei nā ʻenehana ikehu maʻemaʻe e kū mai ana i nā manawa kūpono hou nokalaka siliconpauka liʻiliʻi.

ʻO nā hiʻohiʻona penei:

• Nā mea hoʻohui alakaʻi pila

• Nā mea anode hui

• Nā keramika wahie wela kiʻekiʻe

• Nā ʻōnaehana hoʻololi a me ka hoʻokele wela

I ka wikiwiki ʻana o ka hoʻohana ʻana i ka EV, e hoʻomau ka hoʻonui ʻana o ka pilina ma waena o ka semiconductor-grade SiC a me nā ʻōnaehana mālama ikehu.

5. Hana Hoʻohui a me nā Mea Hana Hui

I kēia manawa, he kuleana ko ka SiC micropowder i ka hana hoʻohui (AM), ʻoiai no ka paʻi 3D ceramic a me nā composites matrix metal.

ʻO nā pono e komo pū ana:

• Hoʻonui ʻia ka ikaika mīkini

• Kaumaha haʻahaʻa me ka hoʻonui ʻia o ka paʻakikī

• Ke kūpaʻa kiʻekiʻe a me ke kūpaʻa oxidation

Hoʻohana kēia mau mea i nā noi aerospace, pale kaua, a me nā kaʻa kahi e koʻikoʻi ai ka lōʻihi o ka māmā.

6. Nā Hana Hana Optical & Infrared

Loaʻa iā SiC nā waiwai optical maikaʻi i nā nalu infrared, e hiki ai ke hoʻohana ʻia i loko o:

• Nā puka makani IR

• Nā ʻāpana wela pae lewa

• Nā mea ʻike a me nā mea ʻike

• Nā uhi pale

Pono kēia mau mākeke i nā mea i hiki ke ola i ka haʻalulu wela a me ka radiation lewa.

7. Nā Noi ʻenekinia Kaiapuni a me nā Kemika

Ma muli o kona inertness kemika, kākoʻo pū ka SiC micropowder i ka kānana wai ʻoihana a me nā ʻōnaehana hana kemika.

ʻO nā hiʻohiʻona penei:

• Nā membrane kānana seramika

• Nā mea lawe mea hoʻoulu

• Nā kiwikā a me nā sila pale i ka palaho

• ʻenehana wai hoʻoneoneo ʻoihana

Manaʻo ʻia he mea kūpono nā membrane keramika SiC i nā ʻōnaehana kānana ukana kiʻekiʻe ma muli o ka haʻahaʻa o ka haumia a me ke ola papa lōʻihi.

Nānā i ka Mākeke a me nā ʻAno Hou e Hiki Mai Ana

ʻO kakalaka siliconManaʻo ʻia e ulu nui ka ʻoihana i loko o nā makahiki he ʻumi e hiki mai ana, i hoʻokele ʻia e:

• Ka hoʻohana ʻana i ka semiconductor kaʻa uila

• Ikehu hou a me nā mea uila mana

• Hana ʻana i nā optics kikoʻī a me ka hana wafer

• Nā keramika hana kiʻekiʻe

• Nā mea māmā no ka mokulele

Ua wānana nā mea kālailai i ka ikaika o ke koi no nā micropowders ultra-fine, spherical, a me ultra-high-purity i ka hoʻonui ʻana o nā noi kiʻekiʻe.

Hopena

Mai nā noi abrasive kuʻuna a hiki i nā ʻenehana semiconductor a me ka ikehu o ka hanauna e hiki mai ana, ke ulu nei ka silicon carbide micropowder i mea hiki ke hoʻokō i ka hana hou o ka ʻoihana hou. I ka hahai ʻana o nā ʻoihana i ka pono kiʻekiʻe, ka pololei, a me ke kūpaʻa, e hoʻonui ʻia ke kuleana o ka SiC micropowder ma nā ʻāpana i hoʻokumu ʻia a me nā ʻāpana e kū mai ana.
