Nā ʻikepili mai kahi pycnometer no nā ana ʻana ma luna o ka laʻana maʻemaʻe (Brass a Zirconia) a me nā laʻana i hoʻohaʻahaʻa ʻia i mālama ʻia ma 300 °C a me 600 °C.
Ua mālama ʻia nā laʻana keramika i ke ana ʻano like ʻole no nā laʻana maʻemaʻe a hoʻohaʻahaʻa ʻia (300 °C a me 600 °C).Manaʻo ʻia kēia ʻano e ka Zirconia ma muli o ka hoʻopaʻa ʻana o ka electrovalent o ka hāʻawi ʻana i nā mea i kona kemika a me ke kūpaʻa.
Manaʻo ʻia nā mea i hoʻokumu ʻia ʻo Zirconia kekahi o nā oxide paʻa loa a ua hōʻike ʻia e hoʻoheheʻe mālie ʻia i nā mahana kiʻekiʻe kokoke i 1700 °C.No laila, ʻo ka hoʻohana ʻana i ka ceramic centerpost no nā noi wela kiʻekiʻe ke koho naʻauao, ʻoiai ke ʻano o ka sintered.

Hōʻike ka ʻaoʻao hema i nā laʻana metala o ka maʻemaʻe a me 600 °C a ʻo ka ʻaoʻao ʻākau e hōʻike ana i ka ceramic pristine a me 600 °C.
Hōʻike ka kiʻi ʻekolu i ke kiʻi hoʻonā kiʻekiʻe o nā mea hoʻohālike i poni ʻia a i kālai ʻia.E like me ka mea i ʻike ʻia, ʻaʻohe mea hōʻike o ka hoʻohaʻahaʻa ʻana i nā kiʻi seramika (nā kiʻi ʻaoʻao ʻākau).Loaʻa i nā laʻana ke ʻano kino like ʻole e hāʻawi i ka paʻa o ka hāpana ceramic i ka wela kiʻekiʻe.Ma ka ʻaoʻao ʻē aʻe, ʻike mākou i ka loli nui o ka morphology o ka ʻili ma nā ʻāpana keleawe i hoʻohaʻahaʻa ʻia.Hoʻohaʻahaʻa ʻia ka ʻili o ka hāpana keleawe e hōʻike ana i ka oxidation kaumaha.ʻO ka hoʻokumu kino ʻana o ka papa oxide i kōkua pū i ka hoʻololi ʻana i ka nui o ka laʻana keleawe.
