Effect of impurities on the microhardness of borax decahydrate

Enhanced electrical properties of BNKT–BMN lead-free ceramics by CaSnO3 doping and their bioactive properties

“…In the current work, the H V and H K values were calculated via eqn (4) and (5).where P = load and d = half-length of the long diagonal. 75–77 The results indicated an increase in H V and H K values as the CSO content increased. Normally, the increases in H V and H K values can be attributed to many factors, such as density and grain size, i.e.…”

“…where P = load and d = half-length of the long diagonal. [75][76][77] The results indicated an increase in H V and H K values as the CSO content increased. Normally, the increases in H V and H K values can be attributed to many factors, such as density and grain size, i.e., a higher density and lower grain size oen produce a higher Vickers and Knoop's values.…”

Influence of SFT Content on Physical, Mechanical and Dielectric Properties of BNKT-SFT Binary Ceramic System

“…The summary of mechanic properties and dielectric at 1kHz room temperature show in table 1. The HV and HK were performed by empirical formula which show in equation ( 1) and ( 2) [11][12]. Each parameter in formula was collected from the indenter print by an optical microscope.…”

Effect of pre-treatments and additives on the improvement of cement wood composite: A review

“…Water vapor is released during decomposition, which is how magnesium hydroxide works as a fire retardant as it creates a layer that insulates the material from the flame (Zhu et al 2016). Boron, which can be regarded as class of eco-friendly materials (El-Batal et al 2019), is used in different fields such as agriculture, glass fiber production, or material processing, but most importantly, in fire retardation (Sayan et al 2010). Boron compounds are the best choice as fire retardants for cellulosic materials.…”
