12136-78-6 Usage

Chemical Properties

Molybdenum silicide is dark-gray, crystalline powder. Not affected by air upto 1648°C. Not attacked by most inorganic acidsincluding aqua regia, but very soluble in hydrofluo-ric and nitric acids. Has high stress-rupture strength.

Uses

Different sources of media describe the Uses of 12136-78-6 differently. You can refer to the following data:
1. MOLYBDENUM SILICIDE can be considered as an electrically conducting ceramic with primary use in heating elements operating at temperatures above 1,500℃ in air. It is also considered as a material for very high temperature structural applications.
2. In electrical resistors, in protective coatings at high temperatures, and in engine parts in space vehicles Molybdenum silicide is used in electric furnaces, glass, steel, electronics and ceramics industries. It finds application in heat treatment materials. It is also used in microelectronics as a contact material. Further, it serves as a dry lubricant.

Application

Molybdenum disilicide (MoSi2) is a ceramic material with excellent high-temperature oxidation resistance and corrosion resistance. It can be used as a substrate material in the fabrication of thermophotovoltaics. MoSi2 can also be used as a protective coating on carbon-carbon composites for potential applications in aerospace and thermonuclear fusion.

Preparation

Molybdenum disilicide is a promising candidate material for high temperature structural applications. Molybdenum silicide is produced in much the same way as ferromolybdenum. A typical mix for the production of molybdenum silicide is 1,000pounds of molybdenum in oxide, 259 pounds of aluminum, 760 pounds of 90-percent ferrosilicon, 166 pounds of 50-percent ferro-silicon, 160 pounds of lime, and 50 pounds of high-grade fluorspar.

Industrial uses

High-temperature silicides are a new class of materials with potential applications in the temperature range 1200 to 1600 C.The silicide that seems most promising is molybdenum disilicide (MoSi2) because of its high melting temperature (2200 C) and excellent oxidation resistance. It has a tetragonal crystal structure. A major problem is its absence of ductility at temperatures up to 1000 C. It also has poor high-temperature strength due to the presence of a grain boundary silicon-rich phase that may become viscous at very high temperatures. Recent research has shown that this problem may be solved by the addition of carbon to the material.

Check Digit Verification of cas no

The CAS Registry Mumber 12136-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,3 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12136-78:
(7*1)+(6*2)+(5*1)+(4*3)+(3*6)+(2*7)+(1*8)=76
76 % 10 = 6
So 12136-78-6 is a valid CAS Registry Number.
