Lanthanum hydroxide does not react much with alkaline substances, however is slightly soluble in acidic solution. [2] In temperatures above 330 °C it decomposes into lanthanum oxide hydroxide (LaOOH), which upon further heating decomposes into lanthanum oxide (La 2 O 3): [4]

[4] In November 2014, the company raised $15 million in Series A Funding, with investors that included GSV Capital and IDG Capital. Seed investors SV Angel and Maveron also participated. [5]
Lanthanum oxide is used in optical materials; often the optical glasses are doped with La 2 O 3 to improve the glass' refractive index, chemical durability, and mechanical strength. [8] 3 B 2 O 3 + La 2 O 3 → 2 La(BO 2) 3 [clarification needed] The addition of the La 2 O 3 to the glass melt leads to a higher glass transition temperature from ...

Naturally occurring lanthanum (57 La) is composed of one stable (139 La) and one radioactive (138 La) isotope, with the stable isotope, 139 La, being the most abundant (99.91% natural abundance). There are 39 radioisotopes that have been characterized, with the most stable being 138 La, with a half-life of 1.03×10 11 years; 137 La, with a half ...
