A rare-earth-containing high-silicon Y-type zeolite, the zeolite contains rare earths, is characterized in that the silicon-aluminum ratio of the zeolite is 5-30, the initial unit cell constant is 2.430-2.465 nanometers, and the balance unit cell constant and the initial unit cell constant The ratio is at least 0.985. The zeolite has the characteristics of small initial unit cell constant and large equilibrium unit cell constant. It has high structural stability and hydrothermal stability. The cracking catalyst containing this zeolite is not easy to deactivate. The choice of gasoline, diesel oil, dry gas and coke Good sex.

The invention discloses an automatic IC testing and sorting device. The device comprises a feeding device, a testing device and a sorting and storing device which are arranged on a machine frame; andthe machine frame comprises a first mounting plate and a second mounting plate, wherein the first mounting plate is vertically arranged, and the second mounting plate is connected with the bottom of the first mounting plate and is obliquely arranged. An IC material tube is clamped on the feeding device, IC chips which are not tested in the IC material tube are supplied to the testing device for testing through the feeding device, after the testing is finished, the chips are classified through the sorting and storing device and are stored in a plurality of empty material tubes. According to thedevice, a clamping mechanism with the IC material tube clamped is turned over, so that the IC material tube is changed into a vertical state, and the IC chips in the IC material tube slide out and get to a vertical material channel; the IC chips can be controlled by a blocking and pressing mechanism to be fed to the testing device one by one, testing chucks clamp the IC chips and push the IC chips to a testing PCB for testing, the IC chips are received through a material receiving table after the test is completed and are classified and placed to a first material storing mechanism or a second material storing mechanism, so that the speed of sorting and storing is increased, and the labor cost is saved.

The gas phase method of extracting aluminum from and supplementing silicon to molecular sieve is to contact molecular sieve with silicon tetrachloride inside one reaction apparatus. The reaction apparatus includes one reactor with material inlet, gas outlet and stirrer, and one gas-solid separator in the gas outlet. The gas-solid separator has suck pore diameter and porosity that the gas can pass through and the solid particle can not. The stirrer has stirring rod extending beyond the reactor hermetically. The contact under stirring has contact temperature of 100-500 deg.c and time of 5-10 min, and the weight ratio between the molecular sieve and silicon tetrachloride is 1 to 0.05-0.5. The said method homogeneous contact reaction between gaseous silicon tetrachloride and solid molecular sieve, no coagulation of solid molecular sieve, less environmental pollution, lowered production cost and other advantages, and is suitable for industrial production.

The invention relates to foam microcrystalline glass produced by using high-silicon iron tailings and a production method of the foam microcrystalline glass. Main raw materials of the foam microcrystalline glass comprise 70%-90% of the high-silicon iron tailings, 0.5%-5% of a foaming agent and 5%-30% of an additive, wherein the foaming agent is obtained by mixing carbon powder and calcium carbonate in a mass ratio being 2:1; the additive is obtained by mixing albite and talc in the ratio being 5: (0.5-1). During production, the raw materials are uniformly mixed, and the foam microcrystalline glass is prepared through preheating, sintering, foaming, crystallizing and annealing processes after forming. The foam microcrystalline glass has the advantages of small density, small heat conductivity coefficient, high compressive strength, easiness in processing and forming and the like and can be used for buildings such as a villa, a civic building, an industrial factory building and the like. The problems of high raw material production cost, complicated technology and the like of the foam microcrystalline glass are solved, pollution hazard of tailing accumulation to the environment is avoided, waste is turned into wealth, and energy saving and environmental protection are realized.
