“…Figure 3 presents FTIR spectra of commercial HfB 2 reagent (Shanghai Aladdin) and as‐prepared HfB 2 sample via Reaction () at 1200°C and after hot water washing. In the case of the latter, the vibrating bands at 1450 cm −1 and 1070 cm −1 are attributed to B‐O‐B asymmetric stretching vibration of [BO 3 ] and Hf‐B overlying [BO 4 ] units, respectively 28−30 , and the characteristic peaks corresponded to Hf‐O around 630cm −1 and 780 cm −1 31,32 , these verified survivals of Hf‐O and B‐O in the as‐prepared sample.…”

“…[4] A fluxing agent with a low melting point is helpful to sinter and form rigid ceramic layers when burning, which is essential in ceramifiable composites. [5,6] Currently, the fluxing agents mainly include glass frit (GF), [7] glass fiber, [8] zinc borate (ZB), [9] and ammonium polyphosphate (APP). [10] Flame retardants generally play the role of isolation and cooling by generating gas, water and compact insulation layer during sintering.…”

Ceramifiable polyolefin materials protect circuits by forming compact ceramic layers under fire conditions, and can have an excellent application prospect in the refractory cable field. In this paper, Aluminum hypophosphite (AHP) and zinc borate (ZB) were added to further improve flame retardancy and ceramifiable properties of polyethylene (PE)/silicon powder (SP)/wollastonite (WS)/ glass frits (GF) composites. The LOI values of composites with AHP/ZB can reach 23.5%, significantly higher than that of PE/SP/WS/GF composites (19.6%). The thermal stability behavior and char yield behaviors of composites could also be characterized by the TG test. The incorporation of AHP/ZB enhances the flexural strength of residue formed at 1000 C from 0.1 to 20.5 MPa. In addition, a new crystal is formed at high temperatures and is identified as the calcium aluminum phosphate phase [CAP, Ca 9 Al (PO 4 ) 7 ] by XRD analysis. The flow of molten ZB accelerates the reaction of AHP and WS, and this eutectic reaction promotes the formation and stability of ceramics. Furthermore, the SEM analysis reveals the fluxing effect of ZB at low temperatures and AHP at high temperatures. The incorporation of AHP/ZB with a ratio of 1:1 could effectively avoid the vitrification of ceramics and improve their dimensional stability.
