Potassium chloride (KCl)

Sodium chloride, Potassium chloride and Potassium bromide single crystals have uniform texture, bright and transparent. They are highly transparent to infrared rays. The thickness is less than 10mm, and the transmittance is more than 90% in the range of 4000-500cm-1. There is no impurity absorption.
It is a broadband good conductor from ultraviolet to mid infrared radiation; Widely used for infrared spectral analysis and the production of ultraviolet and infrared optical components. These single crystals are materials for making optical elements. They can be used as prisms, lenses, filters and transparent materials for various pool windows and laser windows in infrared devices and Optical instrument. At the same time, such crystals are also important thin film substrate materials, especially for the application of "membrane substrate" separation. This type of water-soluble substrate can easily dissolve the substrate with water, leaving only the thin film.

Dihedral Technology(DHD) Co., Ltd. manufacture and processing/provide multiple specifications and high quality KCl crystal,targets,materials.

Applications

It is used to make prisms, lenses, filters, optical elements of various pools and laser windows in infrared equipment and optical instrument, as well as substrate and transport materials of films.

Features

• Potassium chloride (KCl) crystal substrate has high transparency and good optical transmittance from ultraviolet light to far infrared light, which is often used for Infrared spectroscopy research.
It has excellent chemical stability, stable for most acids, bases, salts, and organic solvents, but easily soluble in water.
• Potassium chloride crystal substrate has high thermal conductivity but low mechanical hardness, and is sensitive to mechanical shock and Thermal shock.
• Potassium chloride crystal substrate is easy to cut and polish, which is convenient to prepare high-quality crystal substrate.
• Because it is easily soluble in water, Potassium chloride crystal substrates are often used as disposable or soluble substrates, especially for applications where the substrate needs to be removed without damage or chemical residue.
