Which of the following investment material can be heated up to 1200 degrees centigrade?: (A) Gypsum bonded, (B) Phosphate bonded, (C) Silica bonded, (D) All of the above
Answer is C. 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.
