Good quality quartz glass material , high accurate , many sizes
Quartz glass is good acid materials, except hydrofluoric acid and 300 degrees of above thermal phosphoric acid outside, at high temperatures, it ability sulfuric acid, nitric acid, hydrochloric acid, wang, neutral salt class, carbon and sulfur and erosion, the chemical stability is equivalent to acid ceramic 30 times, equivalent to nickel chrome alloy and ceramic 150 times, it is high temperature resistant, heat resistant shock, coefficient of thermal expansion special small.
