CLEARCERAM™-Z is a glass-ceramic with an Ultra-Low Thermal Expansion Coefficient. This material was developed by OHARA based on our knowledge of High Homogeneity melting and Precise Crystallization. This material is produced under tightly controlled conditions and offers outstanding thermal, mechanical and chemical properties. There are 3 version of CLEARCERAM™-Z available based on thermal expansion differences; Regular, CCZ HS and CCZ EX.
The material shows almost Zero Thermal Expansion over a wide temperature range and offers superior thermal shock resistance. CLEARCERAM™-Z Regular offers lower thermal expansion across a wide temperature range, while the CLEARCERAM™-HS offers lower thermal expansion near room temperature. CLEARCERAM™-Z EX features extremely low temperature dependence of thermal expansion in 0 to 50degree C, which is less than half of the present high spec grade (CLEARCERAM™-Z HS)
The material has very high chemical durability and is very stable in various cleaning and thin-film coating processes. CLEARCERAM™-Z does not contain Na, K, B, F, or Pb in its composition which is a main reason for the excellent chemical resistance the material displays.
The crystal grain structure of the material prevents the propagation of micro crack caused in machining process. This property allows the material to be processed into various shapes with high accuracy, with ease of machinabilty and elevated yield rates.
