摘要： The present disclosure provides a preparation method of a fly ash-based ceramic membrane support, including the following steps: 1) subjecting fly ash to alkali washing and acid washing to obtain pretreated fly ash; 2) blending a raw material including the pretreated fly ash, and then conducting aging and extrusion molding to obtain a green body; and 3) spraying a surface water-retaining agent (including glycerol, tung oil, a diol, and polyethylene glycol) on a surface of the green body to allow static curing in a constant-temperature and constant-humidity environment, and then conducting drying and sintering after the curing is completed. The preparation method can effectively improve molding and sintering performances of the fly ash to obtain a fly ash-based ceramic membrane support with a qualified performance.

摘要： A method for preparing a refractory material from waste battery residues. The method comprises the following steps: (1) disassembling waste batteries, then sorting same to obtain positive and negative electrode powders, leaching the positive and negative electrode powders with an acid, filtering same to obtain a graphite slag, and then subjecting the filtrate to copper removal, followed by the addition of an alkali for a precipitation reaction, wherein the resulting precipitate is an iron-aluminum slag; (2) wrapping the graphite slag obtained in step (1) with wet clay to form an inner core material, then mixing wet clay with the iron-aluminum slag, wrapping the inner core material with same, and aging the wrapped inner core material to obtain a blank; (3) pre-sintering, calcining and cooling the blank prepared in step (2) to obtain a fired product; and (4) washing and drying the fired product to obtain the refractory material.

摘要： A method for manufacturing composite electroceramics comprises obtaining recycled capacitors, coils, resistors, conductors circuit boards, and/or other recycled electronic components. The components may be grinded into a particles having a particle size below 2 mm, and mixed with NaCl powder or Li2MoO4 or other watersoluble ceramic powder having a particle size of 5-200 microns, in a ratio of 10-40 vol-% optionally grinded components, and 60-90 vol-% NaCl powder or Li2MoO4 or other ceramic powder. The obtained solids mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% solids mixture, and 10-30 wt-% aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min, in room temperature, in a pressure of 100-400 MPa. The compressed mass is removed from the mould, thereby obtaining electroceramic composite material. Alternatively to the use of the water soluble salt an organometallic precursor compound can be used.

摘要： The disclosure herein includes methods of preparing ceramic beads, useful as proppant materials, by mixing ceramic precursors, such as slag, fly ash, or aluminum dross, forming bead precursors from the mixture, and heating the bead precursors to drive a chemical reaction between the ceramic precursors to form the ceramic beads. The resultant ceramic beads may be generally spherical particles that are characterized by diameters of about 0.1 to 2 mm, a diametral strength of at least about 100 MPa, and a specific gravity of about 1.0 to 3.0. A coating process may optionally be used to increase a diametral strength of a proppant material. A sieving process may optionally be used to obtain a smaller range of sizes of proppant materials.
