Product Description
Calcium oxide is an inorganic compound，the chemical formula is CaO，the common name of quick lime.The physical property is a white powder on the surface,the impure is grayish white,it is light yellow or gray when containing impurities, and has hygroscopicity. Calcium oxide is an alkaline oxide and is sensitive to moisture. Easy to absorb carbon dioxide and water from the air. Reacts with water to form calcium hydroxide (Ca(OH)2) and produces a lot of heat.
High purity calcium oxide, the choice for industrial upgrading
Changshu Hongyu Calcium Co., Ltd. specializes in producing 90-99% high-purity calcium oxide, providing excellent raw materials for industrial fields such as plastics, rubber, and chemical additives.
Our calcium oxide products strictly control quality, with a purity of up to 90-99%. Extremely low impurity content effectively avoids the adverse effects of impurities on product performance, ensuring the stability and uniformity of downstream products. Whether it is precision plastic products or high-performance rubber products, they can all demonstrate better quality due to our calcium oxide raw materials.
