“…We hypothesized that surface engineering of Ti substrates with potassium hydroxide could form potassium titanate layers on their surfaces. Potassium titanates (K 2 OÁnTiO 2 , n = 2, 4, 6 or 8) have been widely used as fiber-reinforced ceramics and friction materials [11][12][13] due to their good mechanical, thermal and corrosion-resistance properties. Thus, the anticorrosion property of Ti substrates was expected to be improved by protection from potassium titanate layers.…”

“…As above-mentioned, this method permits the control of particle size from micro to nanometric. On this subject, Kang et al [62] reported the synthesis of PHT nanorods, using a reactive mixture of CH 3 OK (95%) and Ti(OC 2 H 5 ) 4 (technical grade) in 20 mL of C 2 H 5 OH, with a molar ratio of 1:1 to 1:2.8 (C 2 H 5 OH to Ti(OC 2 H 5 ) 4 ). To control the competitive reactions hydrolysis and condensation in the medium, distilled water and HCl (35%) were used, and the pH remained in 7.…”

Potassium hexatitanate (PHT) with chemical formula K2Ti6O13 has a tunnel structure formed by TiO2 octahedra sharing edges or corners and with the potassium atoms located in the tunnels. This material has attracted great interest in the areas of photocatalysis, reinforcement of materials, biomaterials, etc. This work summarizes a large number of studies about methods to prepare PHT since particle size can be modified from millimeter to nanometric scale according to the applied method. Likewise, the synthesis method has influenced the material properties as band-gap and the final mechanical performance of composites when the reinforcement is PHT. The knowing of synthesis, properties and applications of PHT is worthwhile for the design of new materials and for the development of new applications taking advantage of their inherent properties.

“…Therefore, recently we have touched gas-influenced impedance of these potassium polytitanate structures at advanced temperatures [ 30 ]. Moreover, one of the essential properties of this material is a possibility to be grown under a variety of morphological forms [ 31 , 32 , 33 , 34 ]. Depending on a ratio of precursors and sintering temperature and/or further treatment, one can tune the crystalline structure and composition of the final product.…”

The Room-Temperature Chemiresistive Properties of Potassium Titanate Whiskers versus Organic Vapors

et al. 2017

The development of portable gas-sensing units implies a special care of their power efficiency, which is often approached by operation at room temperature. This issue primarily appeals to a choice of suitable materials whose functional properties are sensitive toward gas vapors at these conditions. While the gas sensitivity is nowadays advanced by employing the materials at nano-dimensional domain, the room temperature operation might be targeted via the application of layered solid-state electrolytes, like titanates. Here, we report gas-sensitive properties of potassium titanate whiskers, which are placed over a multielectrode chip by drop casting from suspension to yield a matrix mono-layer of varied density. The material synthesis conditions are straightforward both to get stable single-crystalline quasi-one-dimensional whiskers with a great extent of potassium replacement and to favor the increase of specific surface area of the structures. The whisker layer is found to be sensitive towards volatile organic compounds (ethanol, isopropanol, acetone) in the mixture with air at room temperature. The vapor identification is obtained via processing the vector signal generated by sensor array of the multielectrode chip with the help of pattern recognition algorithms.
