Per CLP Regulation, outdated per 1 June 2017. S61: Avoid release to the environment. Flammability code 1: Must be pre-heated before ignition can occur. Health code 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. Reactivity code 0: Normally stable, even under fire exposure conditions, and is not reactive with water. This cement was used in dentistry.

C with a standard oxygen pressure. This reaction is used commercially. The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing ZnO on substrates with cubic lattice structure.

Because of the polar Zn-O bonds, zinc and oxygen planes are electrically charged. This anomaly of ZnO is not fully explained. ZnO is a relatively soft material with approximate hardness of 4. The high heat capacity and heat conductivity, low thermal expansion and high melting temperature of ZnO are beneficial for ceramics. 133 ps at 10 K. An alternative explanation has been proposed, based on theoretical calculations, that unintentional substitutional hydrogen impurities are responsible.
