After all, the purpose of every industry is to provide to the customers, a base which can help them get quality products at affordable costs. Ball lens or half ball using technology is somewhat of this sort, where precision has been brought into the products. Ceramic ball comes in different types and each of the types have a number of uses. Ruby sapphire balls are used where the hardness and anti-corrosiveness are to be featured. These are used as probes in coordinate measuring device, gauging devices, and in floats in flowmeters where precision is utmost important. Cubic Zirconia ball are brands of a type of ceramic ball, which has some unique properties due to which it is used in check valves in flow control instruments. The cubic zirconia ball has the ability to undergo impact in form of grinding, cracking and other pressures, and with that, it undergoes transformation toughening. This means that such types of balls can become stronger as the time and impact goes on. Industrial set ups, all around the world are making use of the special glass ball for various calibrating and precision instruments. Starting from the watches to the various types of laser lights, many types of equipment for precision works are making use of ball lens, or perhaps half ball. Ceramic ball is in much favour due to its hardness and durability and much because of the affordability. These are made of usually silicate, which is a very common component of sand, and this is abundantly available. Many industries are using the ceramic ball to incorporate it into the instruments, and thereby increasing the efficiency as well as the affordability. Similarly, the spinel ball is derived by mixture of magnesium, which is also cheaply available. Due to their capacity to resist extreme temperatures and wear and tear, they are used in variety of industrial applications. With the use of such half ball or ball lens, many instruments are being manufactured, which are being utilised in many products, starting from watches to the medical gadgets. In flowmeters, the glass ball is a common component. Be it a ruby, ceramic, cubic zirconia, or spinel, the materials are quite durable, more than what the steel endures, and therefore such balls have become the buzz word in common man's and industry's use.
