Chemical Name: Aluminum Phosphate Condensed Alias: Aluminum Phosphate Polymerized Aluminum Phosphate
Molecular Formula:AlPO4
CAS No.: 7784-30-7
Physical properties: white powder, odorless, insoluble in water, soluble in nitric acid and hydrochloric acid. As the condensed aluminum phosphate is processed by high temperature condensation, it has excellent thermal stability.
Uses: Widely used in inorganic adhesives, inorganic building materials, ceramics and inorganic molding materials. For example, as a curing agent, it is used in water glass cement and water-based inorganic coatings; Aluminum phosphate powder is mixed with potassium silicate (aka: potassium water glass) for curing, potassium water glass cement is made of potassium water glass, potassium water glass curing agent and acid-resistant filler. As a dispersant, catalyst, melting agent and other additives used in ceramics, high-temperature kiln refractory materials; as a flame retardant, used in plastics, rubber, textiles and other fields. With the expansion of the application field of condensed aluminum phosphate, condensed aluminum phosphate is gradually used in powder coatings, especially high temperature resistant powder coatings and heavy anti-corrosion powder coatings.
Chemical name: Aluminum metaphosphate Alias: Aluminum orthophosphate
Molecular Formula: Al(PO3)3
CAS No.: 13776-88-0
Physical properties: odorless, white powder, insoluble in water and acid, soluble in nitric acid and hydrochloric acid with excellent light transmission properties, is the most stable phosphate.
Uses: used as phosphate optical glass high temperature binder, high temperature lubricant, semiconductor materials, dispersants, and some precision machinery, measuring instruments, such as matrix glass; phosphate optical glass, relative to the silicate, borate series of glass has more excellent physical and optical properties, such as large cross-section of the stimulated emission, low light absorption intensity, good light transmission, and therefore can be used in the manufacture of high-power laser systems, high repetition rate lasers, imaging equipment, and the use of the glass in the manufacture of high power laser systems, high repetition rate lasers. Repetition rate lasers, imaging equipment lenses, advanced cameras and digital camera lenses. It can be used in the manufacture of multi-functional ceramics, as antioxidant for graphite materials after compounding, as adhesive for reinforced composite materials, and with methyl cellulose and calcium silicate for the treatment of wastewater contaminated with heavy metals.
