3 Combustion methodCombustion method is a method of synthesizing materials by combustion of precursors. When the reactants reach the ignition temperature of the exothermic reaction, ignition in some way, the subsequent reaction that is maintained by the heat released, the combustion products are the

1 high-temperature solid-phase methodThe use of high-temperature solid-phase reaction method for the preparation of long afterglow materials is a more traditional method, this method is more widely used. In general, the general operation of the solid-phase reaction is to solid powder as raw material

Evacuation signs should be made of non-combustible materials, otherwise they should be outside with a protective cover made of glass or other non-combustible transparent materials. Cover. In other words, except for the signs made of aluminum alloy and other non-combustible materials as the base mate

Light-storing luminous material is a kind of material that can be stored after receiving light source irradiation and can continue to glow for a period of time without light source irradiation. This material has already appeared in ancient times, known as the luminous pearl, luminous cup is a kind of light storage luminous material.
