| Abstract: | OBJECTIVE: The purpose of this study was to compare the compressive strength of phosphate-bonded investments. METHODS: The three sorts of investments were mixed according to manufacturer's recommendation before poured in the molds. After heated up to 900 degrees C, every sample was mounted on a universal experimental machine to test its compressive strength in ambient. RESULTS: Significant differences were found between the four groups(P < 0.01). CONCLUSION: From the data above it is concluded that the compressive strength of X-20 Chrome Investment mixed with the special liquid was the highest. |
