Muby Chemicals established in the year 1976, is pioneer in Manufacturing Chemicals for Oil and Gas Exploration, Hydraulic Fracturing (Fracking) and coiled tube Chemicals.Our advanced chemistry leading to an innovative and high-performance product range is coupled with effective on and off site management services.
We are manufacturer of Specialty chemicals, Pharmaceutical Excipients, Fragrance & Flavorchemicals in India, which are of IP, BP, USP, Ph. Eur., FCC or Food Grade, ACS, AR or Analytical Reagent Grade, LR or Laboratory Reagent Grade, Pure and Technical Grades of various chemicals.
Zinc dust or powder is a pure metal powder, which is grey in colour and is produced by condensation of purified zinc vapors. We also make Zinc Granules. We supply pure, Pharma synthesis, LR, AR and ACS grades.
Description: Dark Grey, Fine, Metallic Powder or Granules as specified.
Metallic Zinc: 98.0 Min % by wt
Total Zinc (as Zn): 99.5 min % by wt
Lead (as Pb): 50 ppm Max
Iron (as Fe): 100 ppm max
Arsenic (as As): 5 ppm max
Specific Gravity: 7.1 gm/cc3
Particle size D(90): Not more than 80 µm. We can also offer as per buyers requirement.
Assay by Titration: Weigh accurately 50mg of the sample and transfer it into 500 mL of beaker. Dissolve it in 5 mL of concentrated HCl, heat if necessary. Dilute this solution with 200 mL purified water and add Xylenol Orange indicator and sufficient Hexamine to produce violet-pink colour. Add a further 2 gm of Hexamine and titrate with 0.05M EDTA solution using magnetic stirrer until the colour changes to yellow. Determine the assay by using the following formula :
Assay = ( Burette Reading x Factor 3.2695 x Actual Normality x 100) / ( Weight of sample in mg x 0.05)
