Which of the following investment material can be heated up to 1200 degrees centigrade?
Gypsum bonded
Phosphate bonded
Silica bonded
All of the above
When the ethyl silicate–bonded investment is heated to a sufficiently high temperature, some silica converts to quartz and provides added expansion. This type of investment can be heated to between 1090 °C and 1180 °C and is compatible with the higher-fusing alloys. 
Note- Phosphate bonded investment is heated upto 1050 °C.
Closest answer is silica bonded investment materials.
