title: [Preliminary determination of the properties of HX-I refractory die material].
abstract: The setting time, the setting expansion ratio and the compatibility with impression materials of the HX-I refractory die material were determined. The results showed: the setting time was 11 +/- 3 min: the setting expansion ratio was 0.23%; the compatibility with impression materials was excellent between HX-I die material and agar or silicone rubber respectively, but the compatibility was bad between HX-I die material and alginate. These properties of HX-I die material were close to the ones of Lamina die material.
