■ Introduction

1.For partial dentures, framework, and Co-Cr alloy casting.
    Expansion rate: The expansion rate of phosphate bonded investment material may be adjusted by altering the ratio of expansion liquid to water, we can therefore state that:
- Pure liquid gives the maximum setting expansion, meaning the largest casting.
- Diluting the liquid with water will result in the reduction of the setting expansion resulting in smaller castings.
Packing: powder: 400g/packet, liquid: 4L/pot, each carton contains 50 packets of powder and 1 pot of liquid

2.For casting dental crown, bridges and Ni-Cr alloy
Expansion rate: The expansion rate of phosphate bonded investment material may be adjusted by altering the ratio of
expansion liquid to water, we can therefore state that:
- Pure liquid gives the maximum setting expansion, meaning the largest casting.
- Diluting the liquid with water will result in the reduction of the setting expansion resulting in smaller castings.
Packing: powder: 400g/packet, liquid: 3L/pot,each carton contains 30 packets of powder and 1 pot of liquid

3.For casting dental crown and bridges and Ni-Cr alloy, rapid heating
