| manufacturing piezoelectric ceramic capacitors | barium carbonate is widely used in the manufacture of piezoelectric ceramic capacitors such as high voltage AC capacitors and ultrasonic transducer devices. the piezoelectric effect was first discovered by Curie brothers on a quartz crystal in 1880. the crystal that can produce piezoelectric effect is called piezoelectric crystal. A type of piezoelectric crystal is single crystal, such as Shi Ying (SiO2), potassium sodium tartrate (also known as Loser salt, NaKC4H4O6 * H2O), bismuth germanate (Bi12GeO20), etc. Another type of piezoelectric crystal is called piezoelectric ceramic, such as barium titanate (BaTiO3), lead zirconate titanate [Pb(ZrxTirx)O3, code PZT], lead niobium magnesium zirconate titanate made in Japan [Pb(Mg1/3 Nb2/3)O3 added PZT, replace PCM], lead antimony manganese zirconium titanate [Pb(Mn1/2 Sb2/3)O3 added to PIT code PMS] made in China, etc. there are three main types of manufacturing materials for piezoelectric ceramics: lead zirconate titanate raw materials (PbZrTiO3): titanium dioxide, zirconia, lead oxide, strontium carbonate, niobium oxide, lanthanum oxide, etc. lead magnesium niobate raw materials (PbNbMgO3): niobium oxide, magnesium oxide, lead oxide, strontium carbonate, lanthanum oxide, etc. Barium titanate raw materials (BaTiO3): titanium dioxide, barium carbonate, strontium carbonate, etc. |

| production method | carbonization method carbonizes barium carbonate with carbon dioxide gas in barium sulfide solution (see barium sulfide for preparation) to obtain barium carbonate slurry, which is desulfurized and washed, vacuum filtered, dried and crushed at 300 ℃ to obtain barium carbonate finished product. Its BaS + CO2 + H2O → BaCO3 ↓ + H2S ↑ metathesis method is carried out by barium sulfide and ammonium carbonate for metathesis reaction, and then washed, filtered and dried to obtain bismuth carbonate finished product. Its BaS +(NH4)2CO3 → BaCO3 ↓ +(NH4)2S toxic nepheline conversion method reacts toxic heavy stone ore powder with ammonium salt to generate soluble barium salt. At the same time, ammonium carbonate is recycled for use, soluble barium salt is added to ammonium carbonate to precipitate refined barium carbonate, which is filtered and dried to produce barium carbonate finished product. The mother liquor obtained is recycled and recycled. carbonization method. Reaction equation: BaS + CO2 → BaCO3 ↓ + H2S ↑ Operation method: 1L aqueous solution containing 180g/L barium sulfide is reacted with carbon dioxide at 70 ℃ to generate precipitated barium carbonate. The precipitation was mixed with 10ml of 25% ammonia water and desulfurized at 60 ℃ for 20min. After filtration and drying, precipitated barium carbonate is obtained, and the product contains 0.46% sulfur. metathesis method. Reaction equation: BaCl2 + NH4HCO3 + NH4OH → BaCO3 ↓ + 2NH4Cl + H2O operation method: 23.6L aqueous solution containing 56.1g/L ammonium bicarbonate and 1.36L ammonia water are mixed in a 50L kettle at 30 ℃, then 21.6L 200.3g/L barium chloride solution is added dropwise at 50 ℃ for 2h, and stirred at 40 ℃ for 30min. Filtration, drying at 140 ℃, crushing, the average particle size d of barium carbonate is 0.8 μm, and the purity is 99.8%. Tampite method. Reaction equation: BaCO3 + 2NH4Cl → BaCl2 +2NH3 + H2O + CO2 BaCL2 +(NH4)2CO3 → BaCO3 ↓ + 2NH4Cl Operation method: 100 g of 80% arsenite powder (120 mesh) is mixed with 60g of ammonium chloride, and quickly put into a muffle furnace at 650 ℃ for 3min. After cooling, water immersion, filtration, slag removal, barium chloride solution is obtained, 36g ammonium carbonate is added to precipitate barium carbonate, filtration, drying and crushing, and the conversion rate is 91%. dry granulation will be heavy precipitated barium carbonate sieve, placed in the raw material bin fully stirring, mixing, degassing, material through the rotary feeder, horizontal vertical screw conveyor input roller press production, production thickness of 3.7~4mm. The material rolled into pieces is input into the granulator, and the particle size distribution of the semi-finished product is adjusted by adjusting its speed and the size of the sieve plate opening. Semi-finished products are fed into the vibrating screen by scraper pulse pneumatic conveying method. Particles above 20 mesh are returned to the granulator, particles below 65 mesh are returned to the raw material bin, and particles between 65 mesh and 20 mesh are transported to the finished product packaging bin for packaging to produce granular barium carbonate. In the process of wet granulation of barium carbonate production, the water content of the filter cake separated by the sedimentation system is controlled to be about 20%. Under the action of rotating blades, the materials are quickly mixed and evenly, and are mixed and kneaded to form dense particles. The wet particles are put into a direct fire rotary kiln and sintered at 800~1200 ℃. After the whole grain, screening, iron removal, metering packaging, the preparation of granular barium carbonate. |
