Barium peroxide is the inorganic compound with the formula BaO2. This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. Being an oxidizer and giving a vivid green colour upon ignition (as do all barium compounds), it finds some use in fireworks; historically, it was also used as a precursor for hydrogen peroxide.

  • Bariumperoxid ist eine chemische Verbindung der Elemente Barium und Sauerstoff mit der Summenformel BaO2. Beim Erhitzen über 700 °C gibt BaO2 Sauerstoff ab. Bariumperoxid kann aufgrund seiner Verwandtschaft mit dem H2O2 als Oxidations- wie auch als Reduktionsmittel wirken. (de)
  • Il perossido di bario (o biossido di bario) è un composto chimico inorganico con formula BaO2. A temperatura ambiente si presenta come un solido da bianco a giallo chiaro inodore. È un composto nocivo e un ossidante: come molti componenti del bario, il suo innesco dà una fiamma verde brillante, motivo per cui veniva usato nei fuochi artificiali. (it)
  • 過酸化バリウム(かさんかバリウム、英: barium peroxide)はバリウムの過酸化物で、化学式BaO2で表される無機化合物。構造は炭化カルシウムに似る。 (ja)
  • 과산화바륨(영어: barium peroxide)은 화학식 BaO2의 무기 화합물이다. 이 백색 고체(불순물일 때에는 회색)는 가장 일반적인 무기 과산화물 중 하나이며 최초로 발견된 과산화물이다. 산화제이며 분화 시 밝은 녹색을 보이기 때문에 불꽃놀이에 일부 사용되며 역사적으로 과산화 수소의 선구자적 물질로 사용되었다. (ko)
  • Bariumperoxide (BaO2) is het peroxide van barium. De stof komt voor als een wit tot grijswit poeder, dat slecht oplosbaar is in water. Het is een van de meest voorkomende anorganische peroxides. (nl)
  • Nadtlenek baru, BaO2 – nieorganiczny związek chemiczny z grupy nadtlenków. Jest utleniaczem stosowanym m.in. do bielenia i w pirotechnice. (pl)
  • Peróxido de bário (BaO2) é um composto branco cizento. Por facilmente absorver água, é usado como um agente de secagem e também é um agente oxidante que é utilizado para o branqueamento. Ele é usado como pigmento de fogos de artifício, que dá uma vívida cor verde. Este peróxido ao reagir com o ácido sulfúrico pode ser usado para preparar peróxido de hidrogénio através da seguinte reação: BaO2 + H2SO4 → H2O2 + BaSO4 (pt)
  • Перокси́д ба́рия (в просторечии - перекись бария) — химическое неорганическое соединение бария с кислородом, имеющее химическую формулу BaO2. Является производным пероксида водорода. (ru)
  • 过氧化钡(化学式:BaO2)是钡的过氧化物,是最常见的无机过氧化物之一。室温下为灰白色固体,可用作氧化剂、漂白剂。加入至焰火中时既可作氧化剂,也会产生钡特定的亮绿色光。 过氧化钡中含有过氧根离子O22−,固态时与碳化钙(CaC2)有相同结构。 氧化钡吸收O2会生成过氧化钡,该反应可逆,高于700°C过氧化钡分解: BaO + 1/2 O2 ⇌ BaO2 可用该反应来从大气中提取氧气,反应物也可选用氧化钠,机理类似。 过氧化钡与稀硫酸低温反应,过滤,可用于制取双氧水: BaO2 + H2SO4 → H2O2 + BaSO4 (zh)
  • Le peroxyde de baryum est le composé chimique de formule BaO2. Ce solide gris-blanc est l'un des peroxydes inorganiques les plus communs. Le peroxyde de baryum est un agent oxydant, qui est utilisé pour le blanchiment des textiles. Il est utilisé dans les feux d'artifice comme oxydant, et il produit aussi une couleur verte vive, comme tous les composés du baryum. Le peroxyde de baryum est un peroxyde, contenant l'ion O22− où les atomes d'oxygène sont liés entre eux ainsi qu'à l'atome de baryum. Le solide possède la même structure que le carbure de calcium, CaC2. 2 BaO + O2 ⇌ 2 BaO2 (fr)
