nitric acid >55-56%

Nitric acid is a colorless to yellow or red liquid sometimes fuming reddish brown vapors with a suffocating odor. Nitric acid is soluble in water with release of heat. Nitric acid is corrosive to metals or tissue. Nitric acid will accelerate the burning of combustible materials and Nitric acid may even cause ignition upon contact with combustible material. Nitric acid is fully soluble in water and may react violently upon contact with water with the evolution of heat, fumes and spattering. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects

ZINC BORATE 2335 (2ZnO·3B2O3·3.5H2O)

CAS No. 1332-07-6

Product Features:

It is white and nonpoisonous powder. It can be dissolved easily in hydrochloric acid, sulfuric acid, dimethyl sulfoxide etc. but not in water, ethyl alcohol, benzene, acetone etc. It has good dispersibility and stability property. It can be used as flame retardant, meanwhile it can abate smoke. When it is used with Antimony Trioxide, Chlorinated Paraffin -70 together, the effectiveness of flame retardant will be better than ever.

Refractive index



Zinc Borate 2335 has small particle size so that it own average particle distribution and fine dispersion performance. It is suitable to be used in wire and cable as multi-functional synergistic additives with antimony oxide or other halogenated flame retardants to significantly improve the flame retardant performance, remove smoke emission and adjust the balance on chemical, mechanical, electrical etc properties.

Packing and Storage:

25kg/bag, paper-polymer outer & PE inner bag.

Store in dry, normal temperature, moisture prevention.

zirconium powder Industrial Grade 99%

Zirconium metal is available in form of powders, chunks, ingots, lumps, pieces, sheets, foils, particles, slugs, cylinders and targets. It is light gray metal or gray amorphous powder, which is insoluble in water, but soluble in hot concentrated acid, hydrofluoric acid, aqua regia and concentrated sulfuric acid. Zirconium powder would ignite in air when high temperature and turns out zirconium dioxide. The purity of zirconium powder is 99%. The purity of sponge zirconium metal is 99.4%. However the purity of zirconium lump reach 99.9%.

Zirconium Metal

CAS No.: 7440-67-7 EINECS No.: 231-176-9 Molecular Formula: Zr Molecular Weight: 91.224
Melting Point: 1852℃ Boiling Point: 3577℃ Ignition Temperature: >200℃ Density: 6.51


Zirconium metal powder is for preparation of nuclear industry, corrosion resistance alloy, flashlight and fireworks. It also apply to deoxidizing agent for metallurgy and chemical reagents.

The standard size of zirconium slugs are 1.2*3.5mm, 2*3mm and 1.5mm*3mm. The standard thick of zirconium foils are 0.2mm and 0.3mm. The other sizes could be customizable. Both two products are for vacuum coating, which are sputtering targets.
