1. Gịnị bụ graphite isostatic?

Isostatic graphite na-ezo aka na ihe graphite mepụtara site na ịpị isostatic. N'ihi na a na-agbanye graphite dị iche iche na-agbanye n'otu n'otu site na nrụgide mmiri mmiri n'oge usoro ịkpụzi, ihe graphite na-emepụta nwere ihe ndị magburu onwe ya. Kemgbe a mụrụ ya na 1960s, graphite isostatic aghọwo onye ndu n'etiti ihe osise graphite ọhụrụ n'ihi njirimara ya pụrụ iche na ọtụtụ ngwa ngwa.

2. Usoro mmepụta graphite nke isostatic

E gosipụtara usoro mmepụta nke graphite nke isostatically pressed na ọnụ ọgụgụ ahụ. Isostatic graphite chọrọ akụrụngwa isotropic structurally. A ghaghị ịkụnye ihe ndị ahụ ka ọ bụrụ ntụ ntụ ka mma. Ọ dị mkpa ka etinye teknụzụ ịkpụzi Istatic. Usoro ịsa nri dị ogologo.

3. Ngwa nke graphite isostatic

Isostatic graphite nwere ọtụtụ ngwa ngwa, ọkachasị na semiconductor na ubi fotovoltaic.

N'ọhịa nke fotovoltaics, a na-ejikarị graphite eme ihe na graphite components na graphite thermal ubi na otu kristal kristal ọkụ ọkụ na graphite thermal ubi graphite na polycrystalline silicon ingot oven. Kpọmkwem, clamps maka mmepụta ihe silicon polycrystalline, ndị na-ekesa gas maka ọkụ hydrogenation, ihe ndị na-ekpo ọkụ, ihe mkpuchi mkpuchi na polycrystalline ingot heaters, ngọngọ ntụziaka, yana tubes na-eduzi maka otu kristal kristal na nha ndị ọzọ. akụkụ;

N'ọhịa nke semiconductors, ndị na-ekpo ọkụ na mkpuchi mkpuchi maka sapphire otu kristal ibu nwere ike iji ma ọ bụ graphite isostatic ma ọ bụ graphite akpụ akpụ. Na mgbakwunye, ihe ndị ọzọ dị ka crucibles, heaters, electrodes, okpomọkụ na-ekpuchi efere, na mkpụrụ kristal Ihe dị ka ụdị 30 nke njide, ntọala maka crucibles na-atụgharị, efere okirikiri dị iche iche, na efere na-egosipụta okpomọkụ na-eji graphite dị iche iche eme ihe.
