Strontium aluminate is an attractive photoluminescent material that illuminates in the dark when activated with dopants such as europium. As a long-term alternative to copper-activated zinc sulfide, this substance emits various colors such as green (515nm emission wavelength) or aqua (552nm emission wavelength), making it suitable for reusable glow sticks.

1. Material

Strontium Aluminate, the non-toxic and environmentally-friendly luminescent material that has become the go-to choice in glow-in-the-dark pigments for decorative signs and safety signs alike, has taken over as the go-to material to emit light for glow-in-the-dark products like safety signs. Strontium Aluminate’s non-radioactive nature enables it to meet ever increasing consumer demand for safe yet green glow-in-the-dark materials such as signs and decorative materials that emit light for longer. Strontium Aluminate thus meets rising environmental concerns regarding glow-in-the-dark products like safety signs and decorative materials.

Strontium aluminate’s luminescence is powered by electron transfer rather than chemical reactions, making it both non-toxic and eco-friendly. This characteristic makes strontium aluminate an excellent choice when producing glowing materials such as paints and plastics which often contain chemicals which could harm the environment if released into waterways. Furthermore, strontium aluminate can be recycled without losing its luminescent properties over time.

Strontium aluminate pigments are popularly utilized due to their superior luminescent performance, making them suitable for applications including safety signs and decorative materials. Their chemical stability protects them against degradation over time due to changing environmental conditions like humidity or temperature variations; furthermore, these pigments offer resistance against ultraviolet radiation – making them a suitable option for long-term exposure applications like light bulbs and road markings.

Strontium aluminate formulations meet stringent EU environmental standards such as SVHC, further attesting their non-toxic and harmless characteristics. Their low emission levels derived from internal crystal structure and doping levels make them an attractive solution for applications across a range of sectors. Different strontium aluminate variants emit light at different wavelengths; green formulation emitting at 520nm while blue-green variant emitting 490nm light is among them.

2. Color

Strontium aluminate is the brightest and longest-glowing glow-in-the-dark pigment available, replacing copper-activated zinc sulfide in many products requiring high luminosity and long phosphorescence (such as diver’s watches). Additionally, this pigment comes in green (emission at 520nm) or blue-green (485nm) versions which give manufacturers greater options when creating safety signs or consumer goods with this feature. Chemically and physically more stable than zinc-based pigments it stands up well under extreme environmental conditions that would damage zinc-based pigments.

As its luminescence relies on electron transition rather than chemical reactions, this product is environmental friendly and safe for human contact. Furthermore, it does not release harmful substances and can be reused multiple times without losing effectiveness or becoming less vibrant; furthermore it meets European environmental standards as well as SVHC regulations, further attesting its non-radioactive qualities.

Strontium Aluminate boasts an extremely low melting point, making it easy to be cast into various shapes by melting. When coated with protective layers like paint or varnish it becomes even more durable; heat resistance of up to 200degC (392degF). Furthermore, Strontium Aluminate can easily be cleaned using hot water swiping.

3. Size

Strontium Aluminate (SA) is an eco-friendly luminescent material, and meets European Standards such as SVHC for environmental quality. Unlike its first generation luminescent materials like Radium and Zinc Sulfide which emit radiation into the environment through radioactivity, Strontium Aluminate does not emit radiation into its surroundings thereby being nonradioactive and hence nonpolluting to our ecosystems.

Modern glow in the dark paints and plastics utilize this material, as its efficacy as a phosphorescent pigment is superior to copper-activated zinc sulfide; being 10 times brighter and lasting 10 times longer, while also being more cost effective than promethium-based products used previously.

ATT manufactures high purity shot and irregularly-shaped strontium pieces of the highest density and average grain size for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes. We offer standard and doped strontium aluminate rods, ingots, balls, flake powder, powder oxide composite forms as well as custom products to customer specifications – often packaged into palletized plastic 5 gallon pails as full container load (FCL) or truck load (T/L).

4. Finish

Strontium Aluminate (CAS# 12004-37-4) can be obtained in various high purity forms for Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). These forms include shot, irregular shapes, powder, flake granulation processes.

Modern glow in the dark products often use this material as a phosphor replacement, such as replacing copper-activated zinc sulfide with it as well as providing blue-green emission (Eu: Dy) superluminova material for watches and as blue-green emission (Eu: Dy) super-luminova material for watches. Furthermore, some fireworks and glow in the dark paints contain this element as an ingredient.

ATT offers strontium in rod, ingot, ball, tablet form, threads and sputtering targets for various applications. Packaging typically includes palletized plastic 5 gallon pails; steel drums; fiber drums as well as 1 ton supersacks in full container load (FCL) quantities.
