“…However, the atoms in the particles move toward contact points on some of the particulate matter, thus gathering all the particles at lower energy levels. Because the particulate matter is connected by a neck‐shaped structure, sintering further shrinks and densifies, giving the sintering samples mechanical strength . The results revealed lower compressive strength of the porous ceramics at 1000°C.…”

The purpose of this research is to recycle sandblasting waste from the surface treatment process of solar cell industry to replace waste diatomite (with a replacement ratio of 0–20%) to make water‐retention porous ceramics, and adopts the method of molding by semi‐dry pressing under a pressure of 5 MPa, as the heating temperature fluctuated between 1000, 1100, 1200, and 1270°C. With a heating rate of 5°C/min, the heating process continued for 120 minutes. The sintered samples were then examined to determine whether its mechanical properties were met the CNS 382 R2002 Brick Criteria in terms of compressive strength (>3 MPa); while FTIR, and MIP instruments were used to measure the changes in the sintered samples according to pore size and total pore volume. The results indicated that the waste diatomite and sandblasting waste consisted of quartz, and porosities of porous ceramics with sandblasting waste about higher than 58.5–64.7%, water absorption of about 72.2–92.2%, and compressive strength of about 2.4–7.3 MPa can be produced using a porous ceramics of raw materials. The porous ceramics samples with 0–20% sandblasting waste prepared at the heating temperature of above 1100°C meet the Standards for Japan Interlocking Block Pavement Engineering Association (compressive strength > 3 MPa, water absorption > 70%). Moreover, the thermal conductivity of cement paste was 0.57 W/m.K, which was significantly higher than 0.28–0.49 W/m.K of porous ceramics with sandblasting waste, the porous ceramics have good heat insulation effects. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 321–328, 2019

“…With the increasing sintering temperature, the breakage ratio of samples decreased firstly and then increased. It could be seen that the sample of BF 4 possessed the lowest breakage ratio of 2.2%. With increasing feldspar content, the sintering temperature corresponding to the lowest breakage ratio (B. R.) for each composition was decreased gradually 1500°C (the lowest B. R. …”

“…3 In comparison, the ceramic proppant which is produced by conventional technique of solid-state sintering can better meet the demands of lower exploiting cost, higher crushing capability and more uniform size and shape, which are required in the field of proppant materials. 4 In previous research work, more attentions have been paid to pursuing higher strength of ceramic proppant. However, several problems were brought about.…”

The second grade bauxite and feldspar were used to synthesize ceramic proppant materials. Phase structure and microstructure of the samples were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. It was found that the feldspar, as a sintering aid, was beneficial to generate liquid phase during the sintering process. The formed liquid phase, not only promoted the densification of the samples, but also reduced the sintering temperature. With the content of feldspar increasing, the sintering temperature gradually decreased. When the content of feldspar was 4 wt.%, the breakage ratio of the samples was reduced to the lowest level of 2.2% at 1400°C under 52 MPa closed pressure, which met the requirement of Chinese Petroleum and Gas Industry Standard (SY/ T 5108-2014). Moreover, the sintering temperature was reduced by 100°C compared with the proppants without adding feldspar.

“…Although the quartz sand was of low cost and easy to access, it was limited by the 49 50 unfavorable factors, such as low breakage resistance, low level of sphericity, poor diversion ability, etc. [4][5]. In comparison, ceramic proppant possesses high breakage resistance, good diversion ability, high level of sphericity, and so on [6].…”

“…The high sintering temperature will result in high consumption of heat energy [11]. The high density of ceramic proppants will cause difficulties of carrying by the fracturing fluid and increasing the whole cost of the hydraulic fracturing process [5,12]. These phenomena get opposite to the industry pursuit of ceramic proppants with high breakage resistance as well as low preparing cost and low density.…”

A kind of low cost, high breakage resistance ceramic proppant special for exploitation of the coal-bed methane is successfully produced. The producing conditions are optimized through orthogonal experimental design method. The breakage resistance results of the orthogonal analyses show the best condition of this kind of ceramic proppant is A 4 B 3 C 3 D 2 , which means sintering temperature of 1350°C, manganese mineral powder content of 5 wt.%, weight ratio of 75/25 (second grade bauxite to mujie clay), and holding time of 3 h. The ceramic proppants under this very condition of A 4 B 3 C 3 D 2 are then prepared and their phase structure and microstructure are characterized subsequently. X-ray diffraction pattern exhibits that mullite and corundum are the main crystallographic phases. Scanning electron microscopy illustrates the A 4 B 3 C 3 D 2 sample is with non-porous morphology and small amount of corundum grains and liquid phase, which play the role of improving strength. It reveals the orthogonal experimental design is a feasible optimization method and the ceramic proppant made under the condition of A 4 B 3 C 3 D 2 is a promising material for exploiting the coal-bed methane resources.Keywords: Ceramic proppant / optimization / orthogonal experimental design / phase structure / microstructure Schlüsselwörter: Keramische Stützmittel / Optimierung / orthogonaler
