[Optimization on slow-release inhibition of

The hardness and compactness were enhanced and the effective diffusion coefficients reached 2.2849 x 10(-8) cm2/min (R2 = 0.9901) when the mass faction of rosin was 20% and the mass ratio of matrix to calcium carbide was 1/1. Hence,the mitigation the methane generation with municipal solid waste (MSW) can be achieved by the technology of slow-release inhibition.

Question #eabdc | Socratic

Silicon carbide has been used for drill bits and bullet proof vests because of its hardness. Why don't they use diamond instead of silicon carbide? In fact all of these materials (except perhaps for "calcium carbide", which formed the original miners' lamp) are now extensively used as solid-state materials.

Calcium Carbide - an overview | ScienceDirect

The hardnesses of several commonly used abrasive materials are presented in Table 5 to illustrate the position of the carbides relative to other materials. Silicon carbide is harder than the hardest oxides and is, therefore, used in large tonnages as abrasives in grinding wheels, cutting wheels, etc. Table 5. Hardness of several common abrasives.
