摘要

在试验实践中，采用常规方法对12种产自中东欧国家的投资材料的物理性能进行了测试。通过筛分分析评价了其粒度分布，通过渗透、凝固和热膨胀评价了其凝固行为，通过吸水性评价了其初级和次级硬度以及孔隙率。在此基础上对测试材料进行了评价。

[Experimental comparative study on investment materials for casting high-melting dental alloys].

The physical properties of 12 investment materials produced in middle- and east european countries were tested with methods as usual in experimental practice. At that the following properties were evaluated: grain-size distribution by screen-analysis, setting behavior by penetration, setting and thermal expansion, primary and secondary hardness and porosity by water-absorption. On the basis of the results the tested materials are valuated.
