High Temperature Phosphate Investment Material for Precise Casting

The work describes the production of investment material on the basis of β cristobalite obtained from β quartz at 1100°C in the presence of mineralizers. The obtained mixture is characterized by beginning of solidification of 9 min and compressive strength of 6.1 mPa; it provides a smooth surface an...

Description
Summary:The work describes the production of investment material on the basis of β cristobalite obtained from β quartz at 1100°C in the presence of mineralizers. The obtained mixture is characterized by beginning of solidification of 9 min and compressive strength of 6.1 mPa; it provides a smooth surface and easy extraction from the mold of chromium nickel alloys.
