Polished YSZ ZTA Zirconia Ceramic substrate
Zirconia-toughened alumina ceramics, a particle size composition of
the main component of alumina in the preparation of
ceramiccylinder liners for drilling pumps, with an average particle
size of 60-70 wt% in the range of 0.8-1.0 μm and an
averageparticlesize of 30-40 wt% of 1.0 -2.8μm range of two types
of alumina. Add 15vol% of zirconia (containing 2 ~ 3mol% of
yttriumoxide), addappropriate amount of dispersant, mix by ball
milling, spray granulation, isostatic pressing, and fire in the
temperature range of1550 ~ 1620 C, it can be prepared for more than
2000 hours ceramic cylinder liner,and the formingand firing yield
is high, and the raw material and process costs are low. The
performance of zirconia-toughened alumina ceramics is better than
99 aluminaceramics, and the price is much lower than that of
zirconia ceramics.Many occasions where alumina ceramics are
incompetent show a better performance-price ratio than zirconia
ceramics.
