• NIOSH Pocket Guide to Chemical Hazards See morezircon characteristicsApproximately 900,000 tonnes of zirconium ores were mined in 1995, mostly as zircon. Most zircon is used directly in high-temperature applications. Because it is refractory, hard, and resistant to chemical attack, zircon finds many applications. Its main use is as an opacifier, conferring a white, opaque appearance to ceramic materials. Because of its chemical resistance, zircon is also used in aggressive environments, such as moulds for molten metals.

Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2).The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused .

MeSH. D003442. [ edit on Wikidata] In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. [1]Oxygen sensor. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter .Changpeng Zhao (Chinese: 赵长鹏; pinyin: Zhào Chángpéng), commonly known as CZ, is a Chinese-born Canadian businessman.Zhao is the co-founder and former CEO of Binance, the world's largest cryptocurrency exchange by trading volume as of November 2023. He resigned as the CEO in November 2023 after pleading guilty to a money laundering .Zircon is a silicate mineral. It is found in many different places in almost all kinds of rock. The chemical it is made up of is called zirconium silicate: ZrSiO 4. Clear zircon may look like diamond and has been used as a cheaper replacement for diamond. It is not the same as cubic zirconia, which is man-made zirconium dioxide.立方氧化鋯造成的「寶石」. 立方氧化鋯（英語： Cubic Zirconia ，簡稱CZ），亦稱作鋯立晶、方晶鋯石、高碳鑽、泛美鑽、碳鑽、Sona鑽、蘇聯鑽或蘇聯石，是二氧化鋯（Zirconia，ZrO 2 ）晶體的一種。 氧化鋯天然存在時大部份為單斜晶體（mono-clinic），主要以礦物斜鋯石（Baddeleyite）存在。
