There are several companies producing a wide range of balls and half balls using ultra tough materials such as sapphire, ceramic, ruby, spinel, cubic zirconia and optical glass. As a result, these products are extremely long-lasting. Individuals opt for a ceramic ball in their industrial and optical works because it has very low density and curtails abrasion and temperature. These balls can be smoothened to win back their glittering look and thus hold a lengthier lifespan in comparison to other balls. Furthermore, the makers also watchfully render an ideal final polish to generate a striking appearance. Two types of ceramic material are used by certain manufacturers, namely alumina ceramic and zirconia ceramic. The hardness of alumina and zirconia ceramic is 1900 HV and 1200 HV respectively while their fusion temperature is 1500 degree Celsius and 1000 degree Celsius in that order.
Made up of superior quality material together with the most sophisticated technology, the application of glass ball and glass ball lens has gone up in many industries like the chemical industry, electronics industry and pharmaceutical industry. Glass balls are immensely employed in fiber optic connectors, bar code scanners and ball check valves. Glass ball lens produced from diverse materials such as sapphire, spinel and cubic zirconia have top refractive index in conjunction with properties like resistance to scratches and tough surface. They can also be covered with anti-reflection (AR) element to reduce reflection, in that way boosting conduction. These ball lenses are typically constructed in two varieties - the full ball and the half ball. The latter variety is manufactured at a diameter varying from 1.0 mm to 10.0 mm according to customers' requirements. Likewise, the full ball form is devised at a diameter starting from 0.25 mm to 8.0 mm.
These precision balls are exceptionally functional in numerous industrial applications. Their attributes such as electrical insulation, great stability and low compactness amplify the effectiveness of machines. These products are more lightweight than their counterparts used earlier. Hence, they have turned out to be more capable than others.
