| Molar Mass | 181.84 |
| Density | 4.487 |
| Melting Point | 50–60℃ [HAW93] |
| Water Solubility | soluble H2O; insoluble alcohol [HAW93] |
| Appearance | crystalline |
| Physical and Chemical Properties | A colorless, lustrous crystal with deliquescence. Soluble in water, insoluble in alcohol. It is oxidative and can be used for combustion. With the reducing agent can occur a strong reaction, causing combustion explosion. Thermal decomposition of toxic iodide smoke. The Mohs hardness of lithium iodate is 3.5-4. It has a coefficient of linear thermal expansion of 298 · 10 − 5/°C (a-axis) at 2.8 K(25 ° C;77 ° F) and 4.8 · 10 − 5/°C (c-axis). It is irreversibly converted to the beta form at 50°C(122 °F). |

Iodic acid (HIO3), lithium salt - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Application | Lithium iodate (chemical formula: LiIO3) is a negative uniaxial crystal that can be used for nonlinear acousto-optic and piezoelectric applications. It has been used in 347 nm ruby lasers. It is the raw material for the preparation of piezoelectric and frequency-doubled lithium iodate single crystals. Used as an oxidant; used as a medium for generating second harmonics and parametric oscillations in laser technology, and can also be used to manufacture narrow-pulse, broadband ultrasonic transducers with broad prospects in the aviation, chemical, metallurgical and petroleum industries; Used as analytical reagents, catalysts, and oxidants. |
| Preparation | Prepared by the reaction of iodic acid and lithium carbonate. 2HIO3 Li2CO3 → 2LiIO3 CO2 H2O α-LiIO3 crystals were grown by constant temperature evaporation. |
| toxicity | lithium iodate may cause birth defects and should not be used by pregnant women. Frequent use of iodide can cause fetal death, severe goiter and thyroid function decline, and the newborn presents cretinism-like signs. |
| precautions | overview of risks health hazards: this product is toxic. It has a stimulating effect on the skin and mucous membranes. Danger of explosion: This product is combustion-supporting and irritating. first aid measures skin contact: remove the contaminated clothes and rinse the skin thoroughly with soapy water and clear water. Eye contact: Lift the eyelids and rinse with flowing water or normal saline. Medical treatment. Inhalation: Quickly leave the scene to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, artificial respiration is performed immediately. Medical treatment. Ingestion: Drink enough warm water to induce vomiting. Medical treatment. operation disposal and storage precautions for operation: airtight operation with partial air exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety protection glasses, adhesive tape anti-virus clothing and rubber gloves. Stay away from fire and heat sources. Smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Avoid producing dust. Avoid contact with reducing agent. When handling, it should be lightly loaded and unloaded to prevent damage to the packaging and containers. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may remain harmful substances. storage precautions: store in a cool and ventilated warehouse. Stay away from fire and heat sources. The package is sealed. It should be stored separately from easy (combustible) materials, reducing agents, etc., and avoid mixed storage. The storage area shall be equipped with suitable materials to contain leaks. |
| Use | Used as analytical reagent and catalyst Used as oxidant |
