Ethyl Lactate. Ethyl Lactate is an environmentally benign solvent. Lactate esters have found industrial applications in specialty coatings, inks, cleaners and standard cleaning products. The solvent market is estimated at between 3.5 to 4.5 million tonnes per year, at prices ranging from US$ 2.00 to US$ 3.75 per kilo.io-solvents are progressively replacing petrochemical solvents and ethyl lactate serves as a biodegradable and non-toxic solvent which is sought after especially in the field of microelectronics and complies with the quality demands of the semiconductor industry.
Titanium is very expensive because it is awkward to extract from its ores-for example, from rutile, TiO2. You can't use carbon reduction Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent.t has a relatively low density (about 60% that of iron). It is also the tenth most commonly occurri â¦ ng element in the Earth's crust. That all means that titanium should be a really important metal for all sorts of engineering applications. In fact, it is very expensive and only used for rather specialised purposes.
The material cost of a mass produced investment casting item may be 80% of the final cost. The material cost of a single complicated machined item may be less than 10% of the final cost.. It is not possible to provide cost comparisons between different metals to any level of accuracy. Each metal is varying in price on a day to day basis and different alloys of the same metal can have significantly different costs. A grade 7 titanium alloy costs twice as much as pure titanium (grade 1,2 or 3). Comparing costs should only be based on final installed costs. eg. for a domestic, industrial piping system a screwed steel system would cost about 40% more than a copper piping system...
