This material is available at different prices across different vendors in the market. There are a number of websites on which these are being sold. Of course, quality is also just as important as the price at which it is available. The substrate is prepared from sapphire, which is a material with a unique combination of chemical, optical, and physical properties. Sapphire is highly resistant against thermal shocks, high temperatures, sand erosion, and water. Its thermal conductivity is also very good at low temperatures.
