Processing of unglazed ceramic tiles from blast furnace slag

Characterization of Sintered Ceramic Tiles Produced from Steel Slag

“…Figure 1 shows that the values of firing shrinkage decreased with increase in steel slag addition. Apart from tile 1, linear shrinkage of the tested tiles, compared well with values recorded by [4]. Generally, firing shrinkage values increased with higher sintering temperatures due to the densification of samples as a result of sintering.…”

Effects of CaO and Fe₂O₃ on the Microstructure and Mechanical Properties of SiO₂–CaO–MgO–Fe₂O₃ Ceramics from Steel Slag

“…15) Part of these studies focused on the experimental verification of possibility of a certain solid waste substituting for traditional raw materials. 14,18) system ceramics, its sintering mechanism especially microstructure evolution related to CaO and Fe 2 O 3 was still not clear, which is different from that of traditional SiO 2 -Al 2 O 3 -K 2 O (and Na 2 O) system ceramics. The main purpose of the present study was to investigate the effects of CaO and Fe 2 O 3 on microstructure and sintering evolution in the new system porcelain.…”

“…[8][9][10] The ceramics appear a promising solution because it is able to convert, at a relatively low cost, complex chemical compositions into stable crystals or glass phase in ceramics. [11][12][13][14][15][16][17][18] Moreover, ceramics industry also has the ability to consume these bulk solid wastes besides cement and concrete industries. For instance, 10 billion square meter ceramic tiles were produced in China in 2014, the corresponding raw materials consumption was more than 300 million tons.…”

“…In recent years, ceramics prepared from solid wastes or industrial by-production have been studied. The involved solid wastes (industrial by-production) are typically steel slag, 12) blast furnace slag, 13,14,18) municipal solid waste incinerator ashes, 19) and red mud. 15) Part of these studies focused on the experimental verification of possibility of a certain solid waste substituting for traditional raw materials.…”

Preparation of Adsorbent with High Removal Ability for Phosphate Ion from Blast Furnace Slag using Alkali Fusion

“…Blast furnace slag (BFS) is the greatest by-product from pig iron metallurgical furnaces, with approximately 150 million metric ton of slag produced annually worldwide [1,2] . In Japan, more than 25 million tons of BFS is generated each year [3] , and widely used for cement production, road construction, and as a concrete aggregate.…”
