Igwe ọkụ graphite:
A na-eji ihe ndị na-ekpo ọkụ graphite eme ihe n'ime ọkụ dị elu, okpomọkụ ya ruru ogo 2200 na gburugburu ikuku na ogo 3000 na gburugburu gas e tinyere na oxidized.
Isi ihe dị na graphite heater:
1. otu nhazi nke usoro kpo oku.
2. ezigbo ike eletriki na ibu ọkụ eletrik dị elu.
3. iguzogide nchara.
4. enweghị ike ikpochapụ ihe ọkụkụ.
5. ịdị ọcha kemịkalụ dị elu.
6. ike igwe dị elu.
