We are offering 21% lead glass tube. lead glass is primarily composed of silica and lead. It has moderate electrical resistance, density, refractive index and x-ray absorption rate. the softening point of lead glass also tends to lower than that of soda glass. It exhibits moderate durability and is easily worked. mainly used as stem and exhaust tube of fluorescent and incandescent lamp. It is also used for neon signs, pilot lamp, starter lamps and electron gun for tv braun. 1. propertya. coefficient of expansion rate (20-300): 912x10-7/kb. softening point: 63510c. when the mass resistance is 100m.cm, temperature of tk-100240d. density: 2.830.03g/cm3e. strain point: 440f. annealing point: 470g. working point: 1010h. melting point: 1480i. percentage of lead: 21%2. chemical compositiona. sio2: 61.5%b. b2o3: 1%c. al2o3: 1.2%d. pbo: 18-21%e. fe2o3: 0.1%f. lizo: 0.2%g. ba2o: 0.6%
