沉淀硫酸鋇:

?

????沉淀硫酸鋇由硫化鋇溶液與加入經除去鈣、鎂后的芒硝溶液混合，于80進行反應，生成沉淀，經抽濾、水洗和酸洗后，調節pH值56，再過濾，干燥，粉碎制得。亦可用鋇黃鹵與芒硝溶液反應制得。

沉淀硫酸鋇用途:

?

? ? 沉淀硫酸鋇用作油漆、油墨、塑料、廣告顏料、化妝品、蓄電池的原料或填充劑，橡膠制品中既作填充劑，又起補強作用，聚氯乙烷樹脂中作填充劑和增重劑，印像紙及銅板紙的表面涂布劑，紡織工業用的上漿劑。玻璃制品用作澄清劑，能起消泡和增加光澤的作用。可作為防放射線用的防護壁材。還用于陶瓷、搪瓷、香料和顏料等行業。也是制造其他鋇鹽的原料粉末涂料、油漆、?船用底漆、軍械裝備漆、汽車漆、乳膠漆、內外墻建筑涂料、能提高產品耐?光、耐候、耐化學及電化學腐蝕性和產品裝飾效果，增強涂層的抗沖擊強度。無機工業用作制造其他鋇鹽如氫氧化鋇、碳酸鋇、氯化鋇等的原料。木材工業生產木紋印刷板時用于打底和調制印刷漆料。有機合成中作為綠顏料和色淀生產體質填料。

????印?刷油墨填料，能起到耐老化、耐暴曬，增加附著力、色澤清晰、鮮艷、不褪色的作用。

????填?料輪胎橡膠、絕緣橡膠、膠板、膠帶、工程塑料中能增強產品的抗老化性能和?耐候性，產品不易老?化變脆，并能顯著**表面光潔度，降低制作生產成本，作為粉末涂料的主力填料，是調節粉體容重提高上粉率的主要手段。

????功能材料造紙材料、阻燃材料、防X射線材料、蓄電池陰極材料等。均能表現出?獨特的性能，是相關材料不可缺少的重要組成部分。

????其他領域陶瓷、玻璃原料、特種樹脂摸具材料、特殊粒徑分布的沉淀硫酸鋇與鈦復配，對鈦有增效作用，進而減少鈦的用量。

注意事項：

?

? ? 1、儲存于陰涼、通風的庫房。遠離火種、熱源。應與易燃物、還原劑分開存放，切忌混儲。

? ? 2、貯存于干燥的庫房中。作白色顏料時，不可與有色物品共貯混運，以防沾染顏色，裝卸時要輕拿輕放，防止包裝破損。

? ? 3、儲區應備有合適的材料收容泄漏物。
