Product Overview & Quality

Product Name: Lanthanum oxide
Brand: Kemaus (Product Code: KA-1539)
Grade: Laboratory Grade (Lab Grade) with an ultra-high premium purity of 99.9 percent. Strictly manufactured under Kemaus quality control to guarantee absolute consistency and minimize trace metal contamination. Highly suitable for advanced materials research, university laboratories, and industrial R&D.
Physical Properties: Odorless, fine white powder. It acts as a strong base oxide and is insoluble in water.
Solubility: Insoluble in water (reacts very slowly with moisture); readily soluble in dilute strong acids.
Key Use: Widely utilized as a high-purity precursor for synthesizing advanced materials and other lanthanum-based compounds. Heavily applied in materials science and optoelectronics for fabricating optical glass, high-performance camera lenses, and specialized technical ceramics to enhance refractive index. Also serves as an effective catalyst in specific organic synthesis and petrochemical applications.

Safety & Hazards

Classification: Not classified as a severe hazardous substance under GHS regulations. Acts as a mild physical and mechanical eye and respiratory irritant due to its fine dust template.
Health Risks: Direct eye contact with fine dust causes temporary mechanical irritation, watering, or redness. Inhalation of airborne dust may cause coughing, sneezing, or mild upper respiratory tract discomfort.
First Aid Measures: Flush eyes immediately with plenty of flowing water for at least 15 minutes. Wash affected skin with soap and water. Seek medical advice if irritation develops or persists.

Handling & Storage

Storage: Hygroscopic and air-sensitive. It readily absorbs atmospheric moisture and carbon dioxide gas, converting slowly into hydroxide or carbonate forms. Must be stored in the original, tightly sealed Kemaus container in a cool, strictly dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius).
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a fine particulate dust mask. Ensure the container cap is secured tightly immediately after each use to protect the absolute purity of the reagent.
