Following the rebound in germanium prices that began in mid-2012, there has been much discussion - and some confusion - over what has been supporting recent price levels.
At the time, raw material shortages were blamed for germanium's sudden upward tear, which moved prices for 5N metal from around USD1250 per kilogram at the start of the year to nearly USD1700 per kilogram by October.
Strategic stockpiling purchases by China's State Reserve Bureau helped raise the price bar, but in the face of falling demand from germanium metal's most reliable consumer, the infra-red (IR) optics industry, many consumers have been increasingly puzzled with each announcement of higher prices.
Manufacturers of IR and thermal imaging systems, an industry that is both highly dependent on military procurement contracts and highly exposed to germanium price volatility, have been feeling the squeeze of government spending cuts and high material costs. And, not surprisingly, this sector has been the most vocal in their frustration over high prices, leading many to lobby producers for lower prices while attempting to substitute germanium from certain lens structures.
In order to understand the confusion over germanium's recent price gains, we must first examine the relationship between the metal, the IR industry and military procurement.
In Part Two, we will look at changes in the consumption of germanium that have been re-shaping the market in order to explain the recent strength of germanium prices. First, though, let's take a brief look at the key driving forces behind the international germanium market.
