“…Johari et al [ 91 ] synthesized clay-based Na 2 ZnSiO 4 (Clay-NZS) materials using silica nanoparticles (SiNP) as a starting material. SiNP was derived from sulfuric acid treatment of halloysite nanotubes and characterized by smaller sizes (50–70 nm) compared to the synthetic ones (200 nm), contributing to a denser structure and higher conductivity ( Figure 10 ).…”

“…Halloysite has been used in metallized-ceramic materials with magnetic properties, while less ceramic products have been proposed for use as fire resistant materials, aggregates, electrolytes or substrates. Additionally, in many cases modification of halloysite led to the improved efficiency of its final properties due to the better deposition or loading capacity produced; HNTS were successfully involved in a broad field of semi-ceramic applications and markets, especially in high-tech products or medicines (e.g., [ 91 ]). This field is rapidly developing and therefore the studies on low-cost HNTS uses in advanced ceramic composites are sure to be enhanced in the future.…”

The increased demands of our rapidly developing way of life lead to the broadening of the ceramic market among other effects. Due to the advanced ceramic properties of halloysite and its abundance, combined with its good synergistic effect with other materials, it has been investigated for multifarious possible applications to produce traditional and advanced ceramics as well as ceramic composites. In this review, a substantial number of studies by several investigators into halloysite-based ceramics were are summarized. The possibilities and limitations of different halloysite-based ceramic materials for future applications are also discussed in this manuscript and new fields of research are proposed. The summarization of published results indicates a constant scientific interest in halloysite-based traditional ceramics and new potential uses in the future. Additionally, investigations on different novel ceramic composites with low cost halloysite nanotubes (HNTS) have rapidly increased, covering different scientific and technological areas. On the other hand, research into advanced ceramics (SiAlONS) has been pursued due to its highly cost effective technology treatments on a large scale.

“…NZS represents an understudied family of oxides. The Adnan group previously successfully synthesized the halloysite clay-derived NZS ceramic that yielded an ionic conductivity of ~10 -5 S cm -1 at an elevated temperature of 500C [59]. The initial works on NZS therefore show that its operability as an SSE is only feasible at elevated temperatures like many oxide-based inorganic ceramics [31,[60][61][62][63].…”
