Sunward Monoclinic Zirconia Powder
We use precise Tetragonal zirconia polycrystalline (TZP) powder manufacturing process to produce sub-micron monoclinic zirconia with higher quality, our TP-0Y zirconia powder is narrow distribution,D90 <0.5um,and no particles are greater than 2um, it could reduce:
(1) Refrection time during calcination
(2) cut manufacturing cost down effectively
(3) Cost down

Note
(1)ICP result is analyzed by SGS OPTIMA 2000
(2)L.O.I is calcined 1000oC for 1hr
(3)The specific surface area is analyzed by ASAP 2010
(4)Particle size and particle size distribution are test by HORIBA LA300
