“…Among the most notable ceramic, considerable interests have been focus on mullite (3Al 2 O 3 •2SiO 2 ) ceramics as prior candidates for application in high-temperature and oxidizing environment recently due to their low cost, high thermal stability as well as good oxidation and corrosion resistance. [26][27][28] Especially, mullite can be synthesized using low-cost Al 2 O 3 and SiO 2 powders as starting materials. Moreover, mullite can be purified easily at a low mullitization temperature.…”

Nowadays, electromagnetic (EM) interference and radiation pollution generated from widespread application of electronic devices, could damage the normal function of electronic equipment as well as humanity. 1-4 Consequently, high-performance EM wave absorbing materials which have drawn increasing attention are now regarded as an effective strategy to eliminate the EM pollution. Carbon-based composites, 5-9 metal-based composites, 10-14 polymer-based composites, 15-19 and ceramic-based composites, 20-24 have been extensively studied for EM wave absorption application. However, applications of carbon, metal, and polymer-based composites are limited at elevated temperatures due to their degraded strength and EM wave absorption under oxidizing and/or corrosive atmosphere. 25 Therefore, ceramic-based composites with lightweight, excellent high-temperature strength, and outstanding thermal-chemical stability, are regarded as the most promising candidates of EM wave absorbing materials for high-temperature applications.

“…The resulting relative density decreases slowly with an increase in fiber content, but remains above 97%, because of the large size of the ceramic bulk that was prepared by HIP, and the relative density is acceptable. The fiber itself is a dense body, and the pores and gaps that decreased the relative density of the composites were distributed mainly in the Ti 3 SiC 2 matrix and around the SiC f [20]. It is difficult to observe these defects in polished specimens because of the self‐lubricating property of the Ti 3 SiC 2 .…”

SiC f /Ti 3 SiC 2 composites were fabricated by hot isostatic pressing using Ti 3 SiC 2 powder and SiC f as starting materials at 1200 • C for 2 h. A maximum flexural strength of 498 MPa and a fracture toughness of 6.76 MPa⋅m 1/2 were achieved for a composite with 5 vol% SiC f and the microhardness reached 1068 HV 1 with 25 vol% SiC f . SiC and Ti 3 SiC 2 are thermodynamically stable according to the Ti-Si-C phase diagram. However, microstructure analysis showed that the SiC f was distributed uniformly in the Ti 3 SiC 2 matrix with an interfacial layer that was composed of TiC and SiC. Elemental Al agglomeration in the Ti 3 SiC 2 matrix occurred in this reaction layer, which was considered the inducing factor for the occurrence of the interfacial reaction. The interfacial reaction was intense with a low fiber content. Oxidation testing suggested that the oxidation rate increased with SiC f introduction. The oxidation mass gain curve plateaued after 15 h.

“…In this study of 5% iron scale, reinforced PP had a dramatic increase in tensile strength compared to pure PP. It was the expected task of the reinforcement particle to act as a stress concentrator and consume the breaking energy (Gao et al , 2019). However, it was necessary to determine well the ratio of the reinforcement.…”

Purpose In this study, waste iron scale, which occurs in high amounts during steel production and contains high amounts of iron element, was used as a reinforcing material in the polypropylene (PP) matrix. Design/methodology/approach In the PP matrix, 33 micron-sized iron scale was added at 5%, 10%, 15% and 20% ratios. The composites were subjected to mechanical and dry sliding wear tests. The wear mechanisms occurring on the wear surfaces were determined by SEM supported by EDS. Tensile testing was performed using a tensile tester. Hardness tests were performed using a Shore-D hardness tester with ASTM-D-22 standards. Findings Composite reinforced with 5% iron scale showed the highest tensile strength. The addition of higher amounts of iron scale particles reduced the tensile strength of the composites compared to PP. Hardness increased from 58 to 64 Shore-D with the increase in scale content. The reinforcement of PP with iron scale increased the dry sliding wear resistance. Originality/value According to the authors’ knowledge, in the literature review, there was no study found on the effect of iron scale reinforcement on PP.
