He aha ka mea e hoʻohana ʻia ai ka beryllium oxide?
ʻOkiuma berylliumhoʻohana ʻia e like me nā ʻāpana semiconductor hana kiʻekiʻe no nā noi e like me nā lako lekiō. Hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha i kekahi mau mea interface thermal e like me ka thermal greUa hoʻohana nā mea hana semiconductor mana i ka beryllium oxide ceramic ma waena o ka chip silicon a me ke kumu hoʻopaʻa metala o ka pūʻolo e hoʻokō i kahi waiwai haʻahaʻa o ke kūpaʻa wela. Hoʻohana pū ʻia ma ke ʻano he keramika kūkulu no nā mea hana microwave hana kiʻekiʻe, nā ʻōmole vacuum, nā magnetrons, a me nā lasers kinoea.
