Zirconia bricks are the material of choice for severe service where conventional ceramics are not sufficient. Their increased properties overcome major challenges for various industries:
① Metallurgy and chemical industry: Corrosion-resistant against molten metals and concentrated acids, which is the reason for their application also in ladles, linings of furnaces and reactor components.
② Aerospace and high-tech manufacturing industry: They are highly resistant to high temperatures and have high levels of purity, which makes them highly desirable for semiconductor components, melting crucibles and aerospace heat shields.
③ Energy and medical applications: Because of their higher functional and thermal characteristics, they are used in solid oxide fuel cells (SOFCs), oxygen sensors and medical applications at high temperature.
Although alumina is cheap, there is a huge performance improvement using zirconia for mission-critical use. Zirconia has far higher fracture toughness with higher resistance to cracking and mechanical shock than alumina. Zirconia also has a higher melting point and higher thermal shock resistance with stability in harsh temperature fluctuations. Zirconia is much more resistant to aggressive acids and bases and thus the optimal option in corrosive environments where alumina is not suitable.
No. Crushed zirconia bricks will not emit toxic substances under normal conditions. It is a safe inert material. Despite fine dust released upon crushing having to be handled with normal precautions like wearing a mask to prevent irritation, it is not chemically dangerous like silica dust. Only with extremely high temperatures or when they react with chemicals like hydrofluoric acid is a volatile gas released.
No. They are made of different compositions having different properties for different uses.
Zirconia (ZrO₂) is a structurally and refractory-stabilized ceramic of high performance, benefiting from an unusual phase transformation in order to provide enhanced strength and fracture toughness for refractory and structural applications.
Cubic Zirconia (CZ) is a manufactured crystal and is virtually a diamond imitation found in jewelry or as an optical lens. It is neither a refractory nor a structural ceramic.
Zirconia bricks are more costly initially. High-energy raw material refining is used to produce high-purity zirconia, and others, like ultra-fine grinding, cost more than with other ceramics. But zirconia can bring a long-term return, for the high wear resistance reduces maintenance and replacement costs, resulting in significantly longer equipment life with enhanced operating efficiency.
