Product Description: High purity alumina series for new energy battery separators
WHA-301 is high-purity ultrafine alpha phase alumina,which is in the form of a white powder with uniform particle size,high thermal stability,and good chemical stability.It can significantly improve the puncture strength of the battery cell,enhance the compatibility between alumina and electrolyte,improve the liquid absorption and retention capacity ofthe diaphragm,and increase the ion transport rate.At the same time,different processes were used to develop the WHA-302~308 series of high-purity alumina,which is used in various fields such as tricolor fluorescent powder,long afterglow fluorescent powder,gemstones,high-pressuresodium lamps,glass additives,electronic ceramics,catalyst carriers,etc.Due to its excellent physical properties,it can achieve satisfactory results for corresponding customers.
1.WHA-301 is specifically used for new energy battery separators and can also be used for various electronic ceramics.Due to its fineand uniform particle size,the particle morphologyis a regularshape.It can achieve electrical insulation,thermal stability,chemical stability,etc.of battery separators.
2.WHA-302 is specifically used for high-purity alumina powders such as long-lasting fluorescent powders and coatings.Its inherent excellent physical properties can effectively improve the morning afterglow and height indicators of luminescent powder.
3.WHA-303 is a high-purity alumina powder specifically designed for tricolor phosphors.Due to its regularparticle size,fine and uniform particles,and good flowability,it can meet the relevant indicators of blue and green powders in the three primary colors.
4.WHA-304 is high-purity alumina powder for gemstones.Due to its high purity,regular spherical or elliptical particle morphology,and excellent fuidity,it is more suitable for the requirements of relevant indicators of alumina powder for gemstones.
5.WHA-305 is high-purity alumina powder used for high-pressure sodium lamps.As a high-purity material for preparing high-pressure sodium lamps,its high purity,narrow particle size distribution,and excellent sintering activity can meet the relevant requirements of alumina powder for sodium lamps.
6.WHA-306 is a high-purity alumina powder specifically used for catalyst support.Its superior high-temperature stability and high high-temperature activity have improved the service life of high-purity alumina powder used as a carrier.
7.WHA-307 is high-purity alumina powder used as an additive for glass and specialty glass.The presence of trace amounts ofFe and transitional element impurities can enhance the performance of related glass products.
8.WHA-308 isa generally low-gradehigh-purity alumina powder.Its purity ranges from 99.5%to 99.9%,
which can meet the corresponding customer requirements at low cost and has a good performance price ratio.
