Zirconia Mortar and Pestle Description
Zirconia is a crystalline solid that is white in colour, but can be produced in different colours to be used as an alternative gemstone to diamond or as ceramic dental crowns in medical applications. Naturally, it occurs as the translucent (sometimes transparent) mineral baddeleyite, a rare mineral that has a monoclinic prismatic crystal structure; i.e. a mineral having unequal vectors. Also known as "ceramic steel", this oxide of zirconium is chemically inert and is considered as one of the highly auspicious restorative materials, due to its excellent mechanical properties.
Out of all advanced ceramic materials, zirconia has the highest toughness and strength at room temperature. At high temperatures, zirconia may go through substantial change in volume during phase transformation. As a result, it is difficult to obtain stable zirconia products during sintering, which is why stabilisation of zirconia is generally required. Stabilised zirconia adds to the exceptional mechanical properties and chemical inertness a high level of chemical stability, even in harsh environments. Related materials include yttria-stabilised zirconia (YSZ), calcia-stabilised zirconia (CSZ), magnesia-stabilised zirconia (MSZ), etc.
Zirconia's high density, low porosity, inertness, toughness, and super hardness make it the perfect material for making mortars and pestles. Being approximately 10 on the Mohs hardness scale, zirconia mortar and pestles are able to grind materials which are too hard for agate, alumina, or porcelain. Our high wear-resistant mortar and pestle effectively eliminates product contamination and is chemically inert to acids and alkalis.
