Machinable Ceramics
           
Ultra High Temperature Machinable Ceramics
           
For very high temperatures or where thermal conductivity or thermal shock is important, our machinable alkaline earth zirconium phosphate ceramics are recommended. MC-LD is a lower density material suitable for use where thermal shock resistance is important. MC-MD is a higher density material that is superior where better abrasion and wear resistance are desired. These materials can be used to 2700°F (1500°C), can be water quenched from 2550°F (1400°C), and have a very low thermal conductivity of just 1.0
W-mK°.
