The high temperature tetragonal form can be stabilized at room temperature by addition of various oxides, including yttria, ceria, calcia or magnesia [22-23].
(125) is also capable to produce ceria particles doped with zinc oxide or calcia, while the microwave-assisted synthesis can be used for a Ce[O.sub.2]-Si[O.sub.2] composite material.
The XRD patterns showed a pure crystalline calcia or burnt lime CaO (JCPDS card number: 004-0777) for calcination temperatures 700-1100[degrees]C.

It has been shown that introduction of [B.sub.2][O.sub.3] to calcia stabilized zirconia (CSZ) and yttria stabilized zirconia with different amounts of boron oxide improve densification [17, 18].
In this study, test samples were prepared by using Nickel and Titanium with commercial purity according to general requirements of the standard F2063-00 [22] and molded by the melting process under vacuum condition in the vacuum induction melting (VIM) at 1400[degrees]C and in a Calcia (CaO) melting pot, and then they were subjected to cold rolling.
