Photoluminescent Tumbled Gravel production process

Photoluminescent Tumbled Gravel  

I. Features: This is different from the luminous phosphors, which non-radioactive, light long short but luminous efficiency, low cost, colorful.
Second, the device: furnace, crucible, ball mill, drying equipment.
Third, the formula:

Red luminous powder: barium sulfate 55 g, 40 g of magnesium sulfate, lithium phosphate, 2 g of copper nitrate 3 g

Blue luminous: 63 g calcium sulfide, sodium 5 g, 5 g of potassium sulfate, strontium sulfate 10 g, 6 g of sodium chloride, 1 g of silver nitrate, magnesium sulfate 10 g.
Purple luminous: 63 g calcium sulfide, magnesium sulfide 26 grams, 10 grams of sodium sulfide, strontium nitrate 1 g.
Green luminous: 55 g calcium sulfide, potassium sulfide 1 g, 10 g of sodium sulfide, barium nitrate, 12 grams, 13 grams of indium nitrate.
