13825-74-6 Usage
Chemical Properties
White, cake-like solid. Highly acidic,
similar to 50% sulfuric acid, typical composition
20% TiO2, 50% sulfuric acid, 30% water,
hygroscopic. Soluble in water; solutions
hydrolyze readily unless protected from heat and
dilution.
Uses
Different sources of media describe the Uses of 13825-74-6 differently. You can refer to the following data:
1. In tanning; in production of pigment grade and of anatase-structured titanium dioxide.
2. TiOSO4 (titanium (IV) oxysulfate) was used for the preparation of stable amorphous titanium oxide (TiO2) hollow microspheres.
General Description
A colorless or violet colored liquid. Dilution releases heat and may cause precipitation of solid titanium sulfate. Corrosive to metals and tissue. TITANIUM OXYSULFATE is used to make pigments and in dyeing.
Air & Water Reactions
Can generate heat on dilution with water.
Reactivity Profile
A highly acidic liquid.
Hazard
Irritant to skin and tissue.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Safety Profile
A corrosive irritant to
skin, eyes, and mucous membranes. When
heated to decomposition it emits toxic
fumes of SOx. See also TITANIUM
COMPOUNDS and SULFATES.
Purification Methods
Dissolve it in water, filter and crystallise it three times from boiling 45% H2SO4, washing with EtOH to remove excess acid, then with Et2O. Dry it in air for several hours, then in an oven at 105-110o. [Hixson & Fredrickson Ind Eng Chem 37 678 1945.]
Check Digit Verification of cas no
The CAS Registry Mumber 13825-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13825-74:
(7*1)+(6*3)+(5*8)+(4*2)+(3*5)+(2*7)+(1*4)=106
106 % 10 = 6
So 13825-74-6 is a valid CAS Registry Number.

Dielectric properties of zinc doped nanocrystalline calcium copper titanate synthesized by different approach
Singh, Laxman,Rai,Mandal
, p. 2117 - 2122 (2013)
Zinc doped calcium copper titanate, CaCu2.90Zn 0.10Ti4O12 (CCZTO), nanocrystalline electro-ceramics synthesized by solution-wet route (SR) as well as semi-wet route using citric acid (SWR1) and glycine (SWR2) separately, were characterized by TGA/DTA, XRD, TEM, SEM and EDX techniques. The crystallite sizes of the ceramics obtained by XRD were found to be in the range of 45-90 nm is in good agreement with those observed by TEM analysis. The grain sizes for the ceramics SWR1, SWR2 and SR observed by SEM were found in the range of 10-15 μm, 1-4 μm, and 2-4 μm, respectively. Thermal studies show that the single phase CCZTO ceramic was formed in single step combustion reaction in SWR2 while in the case of SWR1 and SR were obtained in multistep reactions. SWR2 route shows more effective solid state reaction for the formation of nanocrystalline CCZTO single phase at much lower sintering temperature. SWR1 ceramic exhibits higher dielectric constant (εr ～ 4317) than SWR2 and SR ceramics at room temperature.
