PD-AG-AU-CU-BASED ALLOY FOR PORCELAIN BAKING |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a noble-metal alloy for porcelain baking for dental casting, which has a low melting point and can enable the use of a gypsum based investment material at casting and has a thermal expansion coefficient lower than 14.9×10<SP>-6</SP>K<SP>-1</SP>. <P>SOLUTION: Combined addition of Ga+In or Sn+In is applied to a Pd-Ag-Au-Cu-based alloy to lower the melting point of the alloy and regulate a thermal expansion coefficient to <14.9×10<SP>-6</SP>K<SP>-1</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
