Nā kikoʻī o -Graphite Maʻemaʻe kiʻekiʻe no nā Semiconductors

Mai ka 5 a hiki i ka 45 microns ka nui o ka ʻāpana, me ka maʻi kalapona ma waena o 99% a me 99.995%.

Nā waiwai o ka graphite ma'ema'e ki'eki'e no nā semiconductor

(1) Kūleʻa wela kiʻekiʻe: Hiki i -Purity Graphite no nā Semiconductors ke kū i nā mahana ma kahi o 2300 degere , me kahi helu heheʻe o 3850±50 degere a me kahi helu hoʻolapalapa o 4250 degere. Ke puhi ʻia i nā wela kiʻekiʻe, emi loa ke kaumaha a he haʻahaʻa haʻahaʻa hoʻonui hoʻonui. ʻO ka mea ʻē aʻe, piʻi kona ikaika i ka piʻi ʻana o ka mahana – pāpālua ia i ka 2000 degere.

(2) Lubricity: ʻO ka nui o ka graphite flakes, ʻoi aku ka maikaʻi o ka friction coefficient a ʻoi aku ka maikaʻi o ka hana lubricating.

(3) Ka uila a me ka wela: ʻoi aku ka maikaʻi o ka lawe ʻana i ka uila ma mua o ka -mea metala maʻamau, a ʻoi aku ka kiʻekiʻe o kona hoʻoiho wela ma mua o nā mea metala e like me ke kila a me ka hao. Ma waho aʻe, e emi ana kona conductivity thermal i ka piʻi ʻana o ka mahana, e lilo ia i mea waiwai maikaʻi loa no nā semiconductor.

(4) Plasticity: Loaʻa iā ia ka paʻakikī maikaʻi; hiki ke ʻōwili ʻia i ʻāpana lahilahi loa a kaomi i ka pepa graphite.

(5) Paʻa kemika: Ma ka lumi wela, hōʻike ia i ke kūpaʻa kemika maikaʻi a hiki ke pale i ka corrosion mai nā waikawa, alkalis a me nā mea hoʻoheheʻe organik.

(6) Thermal shock resistance: Ke hoʻohana ʻia ma ka lumi wela, hiki iā ia ke pale i nā loli wela nui me ka ʻole o ka pōʻino. Ke loli koke ka wela, hoʻololi iki kona leo, no laila e pale ai i nā māwae.

Noi no ka -Purity Graphite no na Semiconductors

(1) No ka hana uila: slurry hoʻoheheʻe uila, hoʻopiha conductive, wahie cell membrane electrode additives, nā mea maka no nā papa bipolar cell cell, conductive agents no ka lithium{1}}ion batteries, stealth shielding coatings, etc.

(2) No ka hoʻoheheʻe wela: ʻO nā mea maka no nā mea hoʻoheheʻe nuklea, nā uhi conductive thermal, nā mea maka no nā kiʻiʻoniʻoni thermal conductive, nā slurries thermal conductive, nā mea hoʻopihapiha hoʻopihapiha hoʻopihapiha, nā mea hoʻohui no ka thermal conductive rubber, etc.

(3) No ka lubrication: Nā lubricants paʻa, nā mea hoʻohui no nā momona a me nā aila lubricating, nā mea hoʻohui hoʻololi i ka lāʻau, nā mea hoʻopaʻa hoʻopaʻa ʻana i ka corrosion -mea hoʻopaʻa, etc.
