A na-eji ihe ndị na-ekpo ọkụ graphite na-ekpo ọkụ na ọkụ ọkụ dị elu na okpomọkụ ruru ogo 2200 na ebe oghere na 3000 degrees na deoxidized na ntinye gas gburugburu.
Isi atụmatụ
1. uniformity nke kpo oku Ọdịdị.
2. ezigbo ọkụ eletrik na ibu eletrik dị elu.
3. nguzogide corrosion.
4. inoxidizability.
5. elu chemical ịdị ọcha.
6. ike n'ibu ike.
Ihe bara uru bụ ike ịrụ ọrụ nke ọma, uru dị elu na mmezi dị ala.
Anyị nwere ike ịmepụta mgbochi-oxidation na ogologo ndụ ogologo oge graphite crucible, graphite ebu na akụkụ niile nke ikpo ọkụ graphite.
