ʻO ka mea huna "ʻeleʻele gula" ma hope o ka ʻoihana semiconductor photovoltaic: ka makemake a me ka hilinaʻi ʻana i ka graphite isostatic

ʻO ka graphite isostatic he mea koʻikoʻi loa i nā photovoltaics a me nā semiconductor. Me ka piʻi wikiwiki o nā hui isostatic graphite kūloko, ua haki ka monopoly o nā hui haole ma Kina. Me ka noiʻi kūʻokoʻa kūʻokoʻa a me ka hoʻomohala ʻana a me nā holomua ʻenehana, ʻoi aku ka maikaʻi o nā hōʻailona hana o kekahi o kā mākou huahana koʻikoʻi ma mua o nā mea hoʻokūkū honua. Eia nō naʻe, ma muli o ka hopena ʻelua o ka hāʻule ʻana o nā kumukūʻai maka a me ka hoʻemi ʻana o nā kumukūʻai e nā mea hoʻohana hope, ua hoʻomau ka emi ʻana o nā kumukūʻai. I kēia manawa, ʻoi aku ka maikaʻi o nā huahana haʻahaʻa haʻahaʻa ma mua o 20%. Me ka hoʻokuʻu mau ʻana o ka mana hana, lawe ʻia nā pilikia hou a me nā pilikia i nā hui graphite isostatic.

1. He aha ka isostatic graphite?

ʻO ka graphite isostatic e pili ana i nā mea graphite i hana ʻia e ke kaomi isostatic. No ka mea ua paʻi like ʻia ka graphite isostatically kaomi ʻia e ke kaomi wai i ka wā o ke kaʻina hana, ʻo ka mea graphite i hana ʻia he mau waiwai maikaʻi loa. Mai kona hānau ʻana i ka makahiki 1960, ua lilo ka graphite isostatic i alakaʻi ma waena o nā mea graphite hou ma muli o kāna mau waiwai kūʻokoʻa a me ka laulā o nā noi.

2. Isostatic graphite hana kaʻina hana

Hōʻike ʻia ka holo kaʻina hana o ka graphite isostatically kaomi i ke kiʻi. Pono ka graphite Isostatic i nā kumu waiwai isotropic. Pono e wili ʻia nā mea maka i loko o nā pauka ʻoi aku ka maikaʻi. Pono e hoʻohana ʻia ka ʻenehana hoʻoheheʻe Isostatic. He lōʻihi loa ka pōʻai ʻala. I mea e hoʻokō ai i ka nui o ka pahuhopu, koi ʻia ka nui o ka impregnation a me nā pōʻai ʻai. , ʻoi aku ka lōʻihi o ka manawa graphitization ma mua o ka graphite maʻamau.

3. Hoʻohana i ka graphite isostatic

Loaʻa i ka graphite Isostatic kahi ākea o nā noi, ka mea nui ma nā māla semiconductor a me photovoltaic.

Ma ke kahua o photovoltaics, isostatically kaomi graphite ua nui hoʻohana 'ia i loko o ka graphite mea i loko o ka graphite thermal kahua i hoʻokahi kristal kelika ulu umu ahi a ma ka graphite wela kahua i polycrystalline silicon ingot umu. ʻO nā mea kikoʻī, nā mea hoʻopili no ka hana ʻana i nā mea hana silikon polycrystalline, nā mea hoʻokaʻawale kinoea no nā umu hydrogenation, nā mea hoʻomehana, nā cylinders insulation a me nā mea wela polycrystalline ingot, nā poloka kuhikuhi, a me nā paipu alakaʻi no ka ulu kristal hoʻokahi a me nā nui liʻiliʻi ʻē aʻe. ʻāpana;

Ma ke kahua o nā semiconductor, nā mea hoʻomehana a me nā cylinders insulation no ka sapphire single crystal growth hiki ke hoʻohana i ka graphite isostatic a i ʻole graphite molded. Eia kekahi, ʻo nā ʻāpana ʻē aʻe e like me nā crucibles, heaters, electrodes, heat-insulating shielding plates, a me nā hua kristal Ma kahi o 30 mau ʻano mea paʻa, nā kumu no ka hoʻololi ʻana i nā crucibles, nā papa pōʻai like ʻole, a me nā pā noʻonoʻo wela i hana ʻia me ka graphite isostatically kaomi.
