I'm looking for glass beads with specific properties. The refractive index should be 1.5 ± 0.05, and I need them to be either white with a rilt or transparent. The desired density is around 2.5 ± 0.1 g/cm³, with a maximum of 20% defective beads. Additionally, the foreign particle percentage, including impurities, should be less than 3%. Also, it's essential that the beads exhibit good resistance to water and various chemicals, such as hydrochloric acid, calcium chloride, and sodium sulfide. For particle size distribution, I require ranges with cumulative refusals of 0-2%, 0-10%, 30-70%, 70-100%, and 95-100% across various micron sizes. Please provide pricing and availability for these specifications.
