“…The glass / ceramic composite was sintered at 750 °C, 800 °C, 850°C, and 900 o C. Before XRD analysis BsGC materials were finely grounded and homogenized. From XRD pattern of samples (Figure 3), we can see that there is a descending trend of quartz peaks (Reference code: 01-078-152) which is the only detected crystalline phase in the investigated samples and it is originated from kaolin that composed mainly of kaolinite mineral and quartz as reported literature [6,24,25]. This observed trend is correlated to the rising in the sintering temperature of glass / ceramic composite samples from 750 to 900 o C. This can be attributed to the reaction of silica with other oxide components in the glass / ceramic composite [26].…”

Borosilicate glass recycling is a challenge because it has high melting point and different chemical structure which makes it non-recyclable in the glass industry. This work focuses on borosilicate recycling through the preparation of a low thermal expansion and chemically durable borosilicate glass-ceramic composite (BsGC). Low thermal expansion and high chemical durability ceramics are advantageous in many applications such as lab supplies, corning ware, automobile components, and other low expansion products that are resistant to thermal shock. Kaolin and borosilicate were chosen for the preparation of glass-ceramic composite, because they have low thermal expansion and good chemical durability. BsGC was prepared by sintering borosilicate glass waste (e.g., Pyrex laboratory glassware, household glass) and kaolin at different temperatures (750-900 ° C). Water absorption method was used to measure the apparent porosity of the prepared composites. Surface morphology of the prepared BCGs was investigated using scanning electron microscopy (SEM). Phase composition of the prepared BGC samples was characterized using X-ray diffraction technique (XRD). The XRD results showed that at sintering of 750 °C a monocrystalline quartz was only existing. By increasing sintering temperature up to 800°C the quartz phase decreased, while at 850 o C the quartz phase completely disappeared. The sintered BCG composites obtained exhibited low coefficients of thermal expansion in the range of 48 x 10-7 o C -1 and exhibited high chemical durability.

“…11 But these aids rarely reduce the sintering temperature to below 1300 C. Another way is to add as much solid waste as possible, such as fly ash, [12][13][14] coal gangue, 4,15 waste ceramic sands, 16 and magnesium slag. 17 The addition of solid waste can not only reduce the sintering temperature but also reduce the preparation cost, but it inevitably reduces the crush resistance of proppants. Therefore, it is particularly important to find a way that can be prepared at lower temperature without reducing the proppants' performance.…”

This study mainly focused on an orthogonal optimization design of low-density and high-strength ceramic proppants prepared by low-grade bauxite and feldspar that met the standard requirements. The orthogonal experimental design of L25 (53) was employed to study the significance sequence of three factors, including milling time of bauxite, milling time of feldspar, and sintering temperature. The results show that the particle size of feldspar is the most important factor for the performance of the proppants. The longer the milling time of feldspar is, the finer the particle size of feldspar is, and the easier it is to form liquid phase at a lower temperature. For the breakage ratio, the optimal experimental combination is bauxite milled for 4 h, feldspar milled for 8 h, and sintering temperature of 1280°C. The proppants prepared by the optimal combination have bulk density of 1.48 g cm−3, apparent density of 2.7 g cm−3, breakage ratio of 4.07% under 52 MPa closed pressure, and acid solubility of 2.15%.

“…Ceramic proppant can be further divided into three broad classifications based on its density: low-density ceramic, intermediate-density ceramic and high-density ceramic [6]. Low-density ceramic proppant is easy to pump and not easy to precipitate, and can reduce the viscosity requirements of the hydraulic fracturing fluid, reduce the damage to the pump, and effectively reduce the difficulty of construction and the cost of exploitation.…”

Calcined flint clay (45.6 wt.% Al2O3) and solid waste coal gangue were used to prepare low-density ceramic proppant by solid state sintering method. The density and breakage ratio of the ceramic proppant were systematically investigated as a function of sintering temperature. The morphology and phase composition of the ceramic proppant were examined by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that the ceramic proppant is composed of rod-like mullite and granular cristobalite. Bulk density and apparent density of the proppant first rise and then slightly decrease with increasing the sintering temperature, while breakage ratios under 35 MPa and 52 MPa pressure gradually decrease and then increase. As the sintering temperature increases up to 1400 °C, the ceramic proppant shows denser microstructure. The proppant sintered at 1400 °C have the best performance with 1.27 g/cm3 of bulk density, 2.79 g/cm3 of apparent density, 3.27 % of breakage ratio under 35 MPa closed pressure and 8.36 % of breakage ratio under 52 MPa closed pressure, which conform to the requirement of low-density ceramic proppant. The addition of solid waste can greatly reduce the preparation cost of the ceramic proppant.
