Advanced functional nanofibers: strategies to improve
In 2017, Li et al. used a modified electrospinning technique, followed by hot-press and calcination to prepare Ni-doped SnO 2 (NTO) nanofiber array for NO 2 detection, as shown in Fig. 6d. It showed a high response (resistance ratio is 90.3 under 20 ppm), fast response and recovery (40 and 18 s), and excellent gas selectivity.In steel industry, calcined lime is used as a fluxing agent for maintaining slag chemistry and basicity by facilitating desulphurization, de-phosphorization. Lime quality and quantity have a direct effect on slag quality which affects metallurgical results, refractory life, liquid metal yield and productivity.

Reductive calcination of calcium carbonate in hydrogen
Calcium carbonate (CaCO 3) minerals represent a valuable resource, but its exploitation is based on the decarboxylation reaction at high temperatures, which inevitably release carbon dioxide (CO 2) into the atmosphere.Here, a reductive calcination of CaCO 3 in the hydrogen (H 2) and methane (CH 4) atmospheres was proposed, [13] Feng J, Li H, Li C X, et al.

The Effect of Lithium Ion Leaching from Calcined Li–Al
A layered double hydroxide (LDH) calcined-framework adsorbent was investigated for the rapid removal of heavy metal cations from plating wastewater. Li–Al–CO3 LDH was synthesized on an aluminum lathe waste frame surface to prepare the sorbent. The calcination treatment modified the LDH surface properties, such as the Used mullite-based saggars from a Li(Ni x Co y Mn z)O 2 (LNCM) materials-making plant were collected to characterize the degradation occurring during application. Based on the post-mortem analysis, laboratory scale experiments were designed using mixtures of mullite powders and commercial Li-ion battery cathode precursors.

Nearly 9.3% is used as a cementitious material (Guo et al., 2018), but only a few cement plants use it to produce clinker. This causes the utilization of steel slag for clinker production in China to be low compared with the US (5%) (Ilyushechkin et al., 2012). 2.3.
