Hunhu uye Mashandisirwo eMakuru Alumina Zvishandiso

Alumina (kemikari formula Al₂O₃) yakakosha inorganic isiri-metallic material ine muviri nemakemikari akanakisa. Inoshandiswa zvakanyanya muindasitiri, zvemagetsi, mushonga, uye mamwe minda. Mafomu ayo makuru anosanganisira -alumina ne-alumina, uye mafomu ekristaro akasiyana-siyana anoratidza misiyano yakakura muzvivakwa nemashandisirwo.

Mhando Huru dzeAlumina Materials

1. -Alumina (Corundum)

-Alumina ndiyo yakanyanya kugadzikana yecrystal fomu yealuminium uye ndicho chikamu chikuru chezvakasikwa corundum (zvakadai serubhi nesafire). Iyo ine dense crystal chimiro, kuomarara kwepamusoro (Mohs kuomarara 9), nzvimbo yekunyungudika yakakwira se2050 dhigirii, uye yakasimba zvakanyanya kugadzikana kwekemikari uye yakanakisa corrosion resistance. Nekuda kwezvivakwa izvi, -alumina inoshandiswa zvakanyanya mukupfekwa-zvisingarambiki, maturusi eceramic cutting, yakakwirira-zvinhu zvinodzivirira kupisa, uye mabearings chaiwo.

2. -Alumina

-Alumina igomba, -pamusoro-nzvimbo yealuminum oxide inogadzirwa necalcining aluminum hydroxide. Chimiro chayo chekristaro chakasununguka chinopa kushambadza kwakanakisa uye chiitiko chinokonzeresa, zvichiita kuti iwande kushandiswa mumagetsi erutsigiro, gasi adsorbents, uye lithium bhatiri separators. -Alumina ine zvakare yakakosha maapplications muceramics, zvinhu zvekupukuta, nezvimwe.

Main Applications yeAlumina

1. Industrial Ceramics

Alumina ceramics, nekuda kwekusimba kwazvo, kuoma, uye yakakwirira-kupindwa nekushisa, anoshandiswa zvakanyanya mukugadzirwa kwemakanika seal, kupfeka{1}}resistant liner, uye maelectronic substrates. -Alumina ceramics anoratidza kugadzikana kunoshamisa, kunyanya munzvimbo{3}}tembiricha, zvichiita kuti aenderane neindasitiri yemhando yepamusoro{4}

2. Electronics uye Semiconductors

Yakakwirira{{0}kuchena alumina (inodarika 99.9%) chinhu chakakosha pakugadzirwa kwezvikamu zvakabatanidzwa zvedunhu, zviumbwa zvinodzivirira simbi, uye zvinhu zvepakeji zveLED. Yakanakisa insulation uye yekupisa conductivity inoita kuti ive chinhu chakakosha muindasitiri yemagetsi.

3. Kurapa uye Zvishongo

Kuomarara kweAlumina kunoita kuti ive chinhu chakanakira majoini ekugadzira nekuisa mazino, ukuwo marubhi nesafire (natural alumina crystals) anoshandiswa mu-zvishongo zvepamusoro pakunaka nekusimba kwazvo.

Mhedziso

Alumina, zvinhu zvakasiyana-siyana, inoita basa rakakosha munzvimbo dzakasiyana siyana, kusanganisira indasitiri, zvemagetsi, uye mushonga, nekuda kweakasiyana mafomu ekristaro. Nekufambira mberi kwesainzi yemidziyo, huwandu hwemashandisirwo ealumina hucharamba huchikura, kunyanya munzvimbo dzesimba idzva, kuchengetedza kwezvakatipoteredza, uye-kugadzirwa kwehunyanzvi hwepamusoro, uko kukosha kwayo kunozonyanya kuoneka.
