What are the optical properties of lithium tantalate?
It is a crystalline solid with unique optical properties such as high surface area, high density and high thermal conductivity. [Sources: 8] Lithium tantalate (LiTaO3) piezoelectric and pyroelectric properties are great for nonlinear optics, passive infrared sensors, terahertz generation & motion detectors, surface acoustic wave applications.
What is the thickness of a lithium tantalate wafer?
After the single- and polarized lithium tantalate crystals are cut with a saw wire, they undergo the lapping process, resulting in a double-sided, lapped wafer with a thickness of 0.4 mm.
Is there a market for lithium tantalate crystals?
According to a recent research report, the global market for lithium tantalate crystals is gaining in luster as we approach the end of the first half of 2017 and the beginning of 2018. It is at this point that we announce the launch of a new lithium tantalate wafer product line, Lithium Tantalates (LTA).
Which is the thermal conductivity of a metal?
Thermal conductivity of common metals, metallic elements aand Alloys Metal, Metallic Element or Alloy Temperature – t – (oC) Thermal Conductivity – k – (W/m K) ” 127 75.5 Iridium -73 153 ” 0 148 ” 127 144
What are the properties of a lithium niobate crystal?
Lithium Niobate Crystal (LiNbO3), also known as LN crystal, is one of the few man-made crystals with many merits, including chemical stability, non-hygroscopicity, a high NLO/EO/AO coefficient, the availablity of large size, and the low cost.
What kind of wafers are used for lithium niobate?
It is also preferable to use wafers that have undergone lapping or at least slicing, or one side of which has undergone mirror polishing to polarize the lithium tantalate crystal into a single one. It is possible to process lithium niobate, which can be used for the manufacture of integrated circuits and other electronic devices.
