Product Introduction

Introduction

High-purity alumina for fluorescent powder, is the main material. The high purity alumina produced by our company has high purity, large output, good dispersion, concentrated particle size distribution, excellent crystal morphology and stable physical and chemical indicators. The resulting LED phosphor has high brightness, narrow particle size distribution, and good crystal shape.

Advantages

1. The high-purity alumina reflects the ultraviolet light that passes through the phosphor layer, so that it continues to excite the phosphor and improves the luminous efficiency.

2. Blocking the diffusion of mercury can reduce the amount of mercury and extend the service life.

3. As a binder, it can improve the bonding strength between the phosphor and the glass tube, so that the phosphor does not fall off.

Feature

1. Chemical properties: high whiteness, no sulfur content, large pine density, weak agglomeration;The ¦ A-alumina obtained has high activity and good thermal shock resistance.

2. Purification technology: the product is purified by high precision technology and made by phase conversion. The product has the characteristics of ultra-fine, high activity, high purity and insoluble in water.

3. Chemical properties: uniform particle size, easy dispersion, stable chemical properties, moderate high temperature shrinkage, good sintering performance;High conversion rate and low sodium content.

4. Physical properties: high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation, corrosion resistance.

5. Application: The obtained particle size of -alumina is neat and does not contain mesophase, and the particle morphology is subspherical and spherical. It is suitable for transparent ceramics, single crystals, luminescent materials and other industries that require the characteristics of alumina.

7. High purity alumina for fluorescent powder, with alumina content greater than 99%;

8. High temperature resistance, normal use at 1600℃, short term at 1800℃;

9. Quench and heat resistance, not easy to burst.
