Measurement of Calcium in Soil - HORIBA The use of accurate Calcium ion testing in controlling the calcium content of soil ensures that the plants which are grown in the soil are given the necessary minerals and can easily absorb water.
Measuring Silicon Carbide Particle Size Due to its high hardness, silicon carbide is used in many abrasive appliions either as a slurry or fixed in a matrix such as grinding wheels. It is also highly abrasion-resistant, so can be used in parts such as nozzles, seals, and bearing components.
