Advanced grinding, smooth, , high hardness yttria-stabilized
zirconia mortar
Description:
Zirconia mortar is mainly used for grinding and analyzing a small
number of samples in the laboratory. It is used for grinding solid
substances or mixing powdered solids.
Application method:
Wash and dry the mortar, and then put the grinding material into
the bowl. First cover the mouth of the bowl with the left hand, and
gently crush the coarse material with the right hand glass pestle,
and then grind. Until the fineness is reached, the grinding
material is poured out from the mouth and continues to grind after
sifting the coarse grain. If you want to make a paste, you can also
use a mortar, the method is the same as above, but because of the
large contact surface of fine particles after grinding, the
dissolution speed is increased, after grinding, the yan distillate
water is directly added in the bowl, to be adjusted into a paste by
the tip of the tip, and finally washed with distilled water, the
washing liquid is also poured into the container.

Advantages:
1. The product has no crack, no impurity and strong resistance to
wear.
2. The product has high gloss and strong corrosion resistance, and
can be used in acid grinding materials.
3. High purity and hardness, which meet the quality and technical
standards.
Advisories and Precautions:
1. In the process of use, special care should be taken to avoid
grinding substances with excessive hardness and contact with
hydrofluoric acid.
2. When grinding, the mortar should be placed on an object that is
not easy to slide, and the pestle should be kept vertical. Large
pieces of solids should only be crushed, not pounded with a pestle,
as this will damage the mortar and pestle or spill solids out.
Explosive materials should only be lightly crushed, not ground. To
grind substances that are corrosive to the skin, cover the mortar
with a thick paper or plastic sheet, then make a hole in the
center, insert a pestle and grind again. The amount of solids in
the mortar should not exceed one third of its volume.
