Ceramics from blast furnace slag, kaolin and quartz

Preparation and Coloration of Colored Ceramics Derived from the Vanadium‐Titanium Slags

“…ey found that a certain amount of slag with other conventional raw materials could be used for sintering at a range of 1100-1150°C. Furthermore, other researchers used industrial waste materials, such as sewage sludge, fly ash, and steel slags, to produce ceramics, cement, and various building materials [4][5][6][7][8]. Simultaneously, vanadium-titanium slags are industrial wastes mainly concentrated in the Panxi area in south-western China.…”

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

“…[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.…”

EFFECT OF CaO/SiO₂ AND HEAT TREATMENT ON THE MICROSTRUCTURE OF GLASS-CERAMICS FROM BLAST FURNACE SLAG

“…A nonuniform diffusion of solute will undoubtedly lead to a non-uniform chemical composition distribution within the glass melt. The viscosity of the parent glass melt has also an obvious impact on the temperature of nucleation and crystallization of the resulting glass-ceramics [7][8]. CaO and SiO 2 , as glass network modifier and glass network former, respectively, are the main ingredients of glass.…”
