12042-68-1 Usage

Chemical Properties

white, monoclinic, tricl, or rhomb; -200 mesh 99% powder(s) [CER91] [CRC10]

Physical properties

Calcium aluminate is a white powder and exhibits a monoclinic crystalline form. Its density is 2.98 g/cc and its melting point is 1605 °C.

Uses

Different sources of media describe the Uses of 12042-68-1 differently. You can refer to the following data:
1. The major use found for CaAl2O4 has been as a hydrous cement. Alternative names are “aluminous cement”, “high-alumina cement” (HAC) and “Ciment fondu”. They are used in a number of small-scale, specialized applications.
2. Calcium aluminum oxide is used as a precursor in the production of naphtha steam reforming catalysts, refinery gas steam reforming catalysts, aluminum chlorohydrate, secondary hydrocarbon steam reforming catalysts. It is also used in the production of refractory and cements.

Preparation

Calcium aluminate can be formed by heating the oxides together at about 900–1250 °C: CaO + Al2O3 + heat→CaAl2O4

Check Digit Verification of cas no

The CAS Registry Mumber 12042-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12042-68:
(7*1)+(6*2)+(5*0)+(4*4)+(3*2)+(2*6)+(1*8)=61
61 % 10 = 1
So 12042-68-1 is a valid CAS Registry Number.

Selective self-redox and crystal field modulation for enhanced and tuned broadband emission in chromium-doped aluminate glasses

Li, Xingyu,Luo, Haoyang,Wang, Yafei,Wang, Xiu,Cao, Jiangkun,Wang, Liping,Peng, Mingying

, p. 5401 - 5409 (2019)

The emerging era of big data has stimulated the development of optical materials with broad emission region to allow data transmission of higher capacity and speed. Here, broadband emission, almost covering the region of 650-1500 nm, was realized by doping transition metal ions into versatile aluminate glasses, in which abundant microstructures and certain oxidizing capacity could be guaranteed to enrich emissions. Furthermore, we aimed to improve spectroscopic properties via the simultaneous self-redox and crystal field modulation of Cr ions and matrixes, respectively. More emission ions and more efficient centers were created to enhance the emission intensity by more than one order of magnitude. In addition, proper crystal field was created to liberate a new emission band at ~708 nm. The results may allow the development of tunable fiber laser and amplifier using the materials and pave the way to precisely control the valence and crystal field to obtain efficient emission.

A mass-spectrometric study of vapor composition and thermodynamic properties of CaO-Al2O3 melts

Shornikov,Stolyarova,Shul'ts

, p. 19 - 22 (2007/10/03)

The composition and partial pressures of molecular species in vapor over melts of CaO-Al2O3 at 1833-2033 K were determined by Knudsen effusion-mass spectrometry. Negative deviations from ideality were observed for the system. The thermodynamic properties of CaO-Al2O3 melts were expressed by analytical dependences as functions of the temperature and concentration of components of the system.
