The invention provides an antimonous oxide powder crystallization system. The antimonous oxide powder crystallization system comprises an antimony white furnace, a reactor, a crystallizer and a powdercollector, wherein the antimony white furnace is provided with an air hose and a feeding opening, a frequency conversion adjustable draught fan is arranged between the reactor and the crystallizer, the crystallizer and the powder collector are connected in a sleeving way and are fixed by using a regulating mechanism, and a low temperature air hose is arranged on the crystallizer. The length of the crystallizer is adjustable, the dwell time of an antimonous oxide material in a crystallization forming section is convenient to control, the crystal form and the grain size of an antimonous oxide power are further controlled, the product specifications of the antimonous oxide are guaranteed to be flexibly regulated on the same production line, the conversion of the crystal form is complete, theproduct quality is further controlled, the low-efficiency investment is avoided, the equipment production line is prevented from being left unused and being wasted, the difficulty in fund flow of theindustry is avoided, and due to the two-section air cooling mode, the whole system reaches rapid quenching, and the product index stably reaches the standard.

The invention discloses a high-tellurium copper slag treatment method. The high-tellurium copper slag treatment method comprises the following steps of: (1) ball-milling; (2) acidifying; (3) low-acid leaching; (4) bismuth precipitating; (5) copper precipitating; (6) high-acid pickling; (7) gold, sliver and lead recycling; (8) solution replacing; (9) antimonium precipitating; (10) tellurium leaching; (11) purifying; (12) neutralizing and tellurium precipitating; and (13) electrolyzing and tellurium extracting. The method disclosed by the invention can be adopted to clean and efficiently treat copper slag, comprehensively recycles noble metals such as gold, silver, tellurium, antimonium, bismuth and copper, and radically solves the problems such as a lagged process, poor comprehensive utilization, a low metal recovery rate and severe environmental pollution of the conventional method.

The invention discloses a lead manganate antimonate (PMS) doped niobium nickel-lead zirconate titanate piezoelectric ceramic (PNN-PZT) having the raw material formula: (1-x)Pb(Ni[1 / 3]Nb[2 / 3])[0.5]Zr[y]Ti[0.5-y]O[3]-xPb(Mn[1 / 3]Sb[2 / 3])O[3], wherein in the formula, x and y represent the molar content and have numerical values respectively being x=0.0-0.06 and y=0.10-0.20. A traditional solid phase synthesis process is adopted, a pre-sintering temperature is 800-900 DEG C, a sintering temperature is 1000-1300 DEG C, and a novel piezoelectric ceramic material is obtained, wherein the material has high piezoelectric coefficient (d33<*>=1000 pm / V) and excellent mechanical properties (E=120 GPa, and K1C=1.44 Mpa.m<1 / 2>). The piezoelectric ceramic based on lead zirconate titanate has high piezoelectric coefficient and excellent mechanical properties. The novel piezoelectric ceramic is mainly used in the fields of micrometric displacement actuators, piezoelectric sensors, transducers and the like, and has great market values.

The invention discloses a preparation device for catalyst-grade antimonous oxide, which comprises an antimony white furnace (1) and a reactor (8). The preparation device for the catalyst-grade antimonous oxide has the characteristics that the inner chamber of the antimony white furnace (1) is provided with a front chamber (2) and a rear chamber (3) which are communicated; the front chamber (2) and the rear chamber (3) are respectively provided with a blowpipe; one end of the blowpipe passes through the antimony white furnace wall to extend into the chamber; the other end of the blowpipe is arranged out of the antimony white furnace (1); the top of the rear chamber (3) is connected with the reactor (8); and the top of the reactor (8) is provided with a crystallizer.
