Antimony Pentoxide Colloidal Sb2O5

Colloidal Antimony Pentoxide is made through a simple method based on reflux oxidization system. UrbanMines has detailedly investigated about the effects of experimental parameters on the colloid stability and size distribution of the final products are carried out. We specialize in offering colloidal antimony pentoxide in a wide range of grades developed for specific applications. The particle size ranges from 0.01-0.03nm up to 5nm.

Colloid Antimony Pentoxide

Synonyms: Antimony Pentoxide Colloidal,Aqueous Colloidal Antimony Pentoxide

Molecular formula: Sb2O5·nH2O

Appearance: Liquid stat, milk-white or light yellow colloid colloidal solution

Stability: Very High

Advantages about Antimony Pentoxide Colloidal Better penetration of the substrate. Less pigmenting or whitening effect for deep mass tone colors Easier handling and processing. Liquid dispersions will not clog spray guns. Translucency for coatings, films and laminates. Easy compounding; no special dispersing equipment required. High FR efficiency for minimal added weight or change in hand.

Antimony Salt Compounds Aluminum Oxide Nanoparticles/Nanopowder 1344-28-1
Aluminum Oxide (Al2O3) is a white or nearly colourless crystalline substance, and a chemical compound of aluminum and oxygen. It is made from bauxite and commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Al2O3 is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.

Antimony Salt Compounds Boron Carbide(B4C) Powder 12069-32-8
Boron Carbide (B4C), also known as black diamond, with a Vickers hardness of >30 GPa, is the third hardest material after diamond and cubic boron nitride. Boron carbide has high cross section for absorption of neutrons (i.e. good shielding properties against neutrons), stability to ionizing radiation and most chemicals. It is a suitable material for many high performance applications due to its attractive combination of properties. Its outstanding hardness makes it a suitable abrasive powder for lapping, polishing and water jet cutting of metals and ceramics. Boron Carbide is an essential material with lightweight and great mechanical strength. UrbanMines’ products have high purity and competitive prices. We also has much experience in supplying a range of B4C products. Hope we can offer helpful advice and give you a better understanding of boron carbide and its various uses.
