“…This glass-ceramic was known as "Slagceram" and it was produced by the conventional, two-stage, heat treatment method [64,65]. A similar material, "Slagsitall", was developed in the former Soviet Union at about the same time [66,67]. More recent works have investigated the effect of adding nucleating agents to the slag; in particular glass-ceramics with acceptable properties were produced using a two-stage heat treatment and addition of titania [68].…”

Glass-ceramics are polycrystalline materials of fine microstructure that are produced by the controlled crystallisation (devitrification) of a glass. Numerous silicate based wastes, such as coal combustion ash, slag from steel production, fly ash and filter dusts from waste incinerators, mud from metal hydrometallurgy, different types of sludge as well as glass cullet or mixtures of them have been considered for the production of glass-ceramics. Developments of glassceramics from waste using different processing methods are described comprehensively in this review, covering R&D work carried out worldwide in the last 40 years. Properties and applications of the different glass-ceramics produced are discussed. The review reveals that considerable knowledge and expertise has been accumulated on the process of transformation of silicate waste into useful glass-ceramic products. These glass-ceramics are attractive as building materials for usage as construction and architectural components or for other specialised technical applications requiring a combination of suitable thermo-mechanical properties.

“…The composition of the zinc borosilicate (ZBS) glass chosen as coating material was (wt-%): 65 ZnO, 22.5 B 2 O 3 , and 12.5 SiO 2 [16]. For preparation of this glass, powders of ZnO, SiO 2 and H 3 BO 3 were mixed together in a platinum crucible and heated for 1 h at 1200 C in air.…”

“…In the present study, a zinc borosilicate glass-ceramic, similar to a material previously reported in the literature, [16] was developed as coating material for SiC f /borosilicate glass matrix composites. The efficiency of the anti-oxidative coating was demonstrated by comparing the results of oxidation tests on the coated composite with those on the as-received (uncoated) composites after heating at 600 C in air for 100 h.…”

the substrate and limit the stress level, 2 air-cooling jets were added to the spray configuration to lower the coating temperature during deposition.Experiments were carried out considering 5 processing parameters: arc current (A), hydrogen ratio (B), total plasma gas flow rate (C), powder carrier gas flow rate (D) and injector diameter (E). The three first parameters are known to influence significantly the plasma jet properties (enthalpy, velocity, etc.) and the last ones influence particle trajectories in the plasma jet. A factorial design L 16 (2 5 ) was used to vary each of these parameters into 2 significant levels tacking into account all possible couple interdependencies as shown in Table 1.Coating friction behaviour characterization: Friction tests were performed using a Pin-On-Disc (POD) arrangement on a CSEM 1 tribometer. The POD test is a model test for determining friction characteristics and wear behaviors of two solid surfaces being in sliding contact. In this study, test configuration corresponded to a single point contact. Before performing the test, the samples were ground to lower their surface roughness (i.e., average roughness less than 1 lm). The coated sample were than slided against a 6 mm ball made of WC/Co under an applied load of 5 N. The sliding contact was maintained at 6 mm from the sample centre. The sample was rotated at 394 rpm corresponding to a linear speed of 0.33 m.s ±1 . The sliding distance was 1000 m reached after 51 min.

“…The present results revealed that, the chemical durability of the investigated vitrified bond Y1.0 was the highest among those in other studied samples. The reason is that the fine microstructure of the vitrified bond Y1.0 makes it possible to count on better chemical durability compared with porous ceramics, which have a more extensive surface and greater penetrability to liquids and vapors [36]. The vitrified bond with 1.0 mol% Y1.0 addition possesses the high chemical durability, which can guarantee CBN abrasive tools safety and service life.…”
