Molybdenum Oxide Price Falls Slightly on Poor Steel Bidding

Chinese molybdenum price remains weak adjustment because steel bidding plans for ferro molybdenum are unclear and the market faces pressure. The latest price of molybdenum concentrate and molybdenum oxide falls slightly.

Inventory shortage in mines stabilizes molybdenum concentrate price; prices and quantity of steel biddings show poor performance and thus ferro molybdenum price is under pressure and manufacturers have strong risk aversion. Due to few new increased orders and weakening support from costs, prices in molybdenum chemical and product market is in a downward trend.

Jiangsu Dragons bid out 150 tonnes of ferro molybdenum in July with price of RMB 105.500 per tonne, down RMB 3,000 per tonne from last month; HBIS Group tenders 60 tonnes of ferro molybdenum for June in RMB 106,500 per tonne, down RMB 1,500 per tonne from compared with last time.

Chinese Molybdenum Price Is in a Downward Trend

Analysis of latest molybdenum market from Chinatungsten Online:

Chinese molybdenum price is in a downward trend at present amid the latest price of molybdenum concentrate and sodium molybdate falls slightly and molybdenum powder price is unchanged from the previous trading day. Weak market demand, poor performance of steel biddings and weakening support from raw material side are the main reasons.

Insiders now are negative on the market outlook and manufacturers cutting their product profits for more orders lower transaction prices. Affected by the environmental checks, the operating rate in mines and smelting factories is low. In the short term, deadlocked supply and demand will continue and steel biddings at the end of this month would be the focus of the market.

Molybdenum Metal & Alloys

Molybdenum metal is usually produced by powder metallurgy techniques in which Mo powder is hydrostratically compacted and sintered at about 2100°C. Hot working is done in the 870-1260°C range. Moly forms a volatile oxide when heated in air above about 600°C and therefore high temperature applications are limited to non-oxidizing or vacuum environments.

Moly alloys have excellent strength and mechanical stability at high temperatures (up to 1900°C). Their high ductility and toughness provide a greater tolerance for imperfections and brittle fracture than ceramicssintered-molybdenum-parts.

molybdenum sheet picture

The unique properties of molybdenum alloys are utilised in many applications:
High temperature heating elements, radiation shields, extrusions, forging dies, etc;
Rotating X-ray anodes used in clinical diagnostics;
Glass melting furnace electrodes and components that are resistant to molten glass;
Heat sinks with thermal expansivity matching silicon for semiconductor chip mounts;
Sputtered layers, only Ångstroms (10-7 mm) thick, for gates and interconnects on integrated circuit chips;
Sprayed coatings on automotive piston rings and machine components to reduce friction and improve wear.

For specialised applications, Mo is alloyed with many other metals:
Mo-tungsten alloys are noted for exceptional resistance to molten zinc;
Mo is clad with copper to provide low expansion and high conductivity electronic circuit boards;
Mo-25% rhenium alloys are used for rocket engine components and liquid metal heat exchangers which must be ductile at room temperature.

Brief Introduction To Molybdenum Electrode

Molybdenum (Mo) is commonly used as back contacts for Cu(In,Ga)Se2(CIGS) thin film solar cells because it has the good molybdenum electrode electrical properties of an ohmic contactand is an inert, mechanically durable substrate duringthe absorber film growth. In general, Mo is deposited bydc sputtering onto soda-lime glass substrates. The elec-trical and the mechanical properties of sputtered refrac-tory metal films are known to vary with the working gaspressure .

molybdenum furnace electrode picture
CIGS thin film growth occurs at tempera-tures > 500  and at these temperatures, the thermallyinduced extrinsic stresses in the glass-Mo structure maycause bending or mechanical distortion of substrate. During the formation of CIGS films, Na ions diffuse fromthe soda-lime glass substrate through the Mo back con-tact into the absorber layer. The diffusion of Na into theabsorber film depends on the deposition conditions of theMo back contact .

Molybdenum films were deposited on soda-lime glass substrates by using DC magnetron sputtering. Their structural and morphological properties and their electrical resistivities were analyzed with respect to the working gas (Ar) pressure. The electrical resistivity of the Mo films monotonically increased as the gas pressure was increased. The films showed a (110) preferred orientation, regardless of the working gas pressure.

The surface morphology of the films changed from an elon-gated grain structure at lower working pressures to a porous nodular shape at higher pressures. The surface roughness of the films increased with the working gas pressure. Secondary ion mass spectrometry data showed that Na diffusion from the soda lime glass substrate through the Moback contact was high, for the film sputtered at 5 mTorr. Cu(InGa)Se2 solar cells fabricated on Mofilms sputtered at 5 mTorr showed the best conversion efficiencies.

"Water and Soil Disease" Caused by Molybdenum Lack

The average contents of molybdenum is 1.3 PPM, in the earth crust. Fossil fuels containing molybdenum in natural water body is in very low concentrations, and molybdenum in sea water of the average concentration is 14 micrograms/l.

molybdenum pollution picture

But due to the Human activities widely used molybdenum and burning of molybdenum content fuel , so increase the molybdenum in the environment circulation.

What is more Weathering make the molybdenum released from the rock. Molybdenum distribution are not regularly, thus cause some areas lack of molybdenum and appear "water and soil disease".

The Weakness in Chinese Molybdenum Price

Chinese molybdenum price is weak amid the price of molybdenum concentrate and molybdenum oxide declines slightly and ferro molybdenum price remains unchanged. Representative miners in Heilongjiang lowered product offers earlier this week, which enhances traders’ negative mentality. Trading atmosphere is quiet at present.

In the molybdenum concentrate market, some sellers with weak market confidence decline product prices for more shipments, but considering the support from supply side, the adjustment is limited. Although the production cost in the ferro molybdenum market shows signs of decline, steel bidding prices are in a relatively low level. Ferro molybdenum manufacturers are caught in heavy wait-and-see atmosphere.

Chinese Molybdenum Market Stabilizes on Weak Demand

The latest price of ammonium molybdate and ammonium heptamolvbdate falls slightly while molybdenum powder price remained unchanged in Chinese molybdenum market. Disparity in supply and demand at each end of the industry chain affects the dissension of businesses and central enterprises operate mainly replying on costs.

Molybdenum concentrate traders are more active in inquiry, which increases market trading. While miners with good mentality keep firm offers. In the ferro molybdenum market, prices of steel biddings change sharply, but still are weak. Risks of cost overhang of manufacturers weaken trading willingness. Weak demand makes businesses selling their products at low prices, so product prices in the molybdenum chemical and product market decline slightly.
