PAM XIAMEN offers SiO2 (single crystal quartz).
Single crystal quartz wafer is an excellent substrate for microwave filters for wireless communication industries.
Conversion from the three-index system to the four as [u ‘ v ‘ w ‘ ] —> [u v t w] is accomplished by the following formulas:
X-cut (110), (-1-10) = (11-20) or (22-40), XRD 2theta is 36.56 or 77.73 degrees
Y-cut (100), (010) (0-10) = (10-10),(20-20) or (30-30), XRD 2theta is 20.86,42.46,65.83 degrees
Z-cut (001) = (0001), XRD 2theta is 50.66 degree or 117.7 degrees
ST-Cut, a rotated Y-cut with rotation 42.5°
AT-Cut, a rotated Y-cut with rotation 35°15′
