Lava (Grade "A") Grade A Lava is a machinable ceramic that exhibits good electrical and heat resistance. Excellent thermal shock properties allow it to be used in applications where long term thermal cycling is a consideration. Low thermal conductivity is also a highlight of this material.fact makes the compressive strengths of the pre-crushed rock shown above even more impressive. As a comparison, residential concrete slabs are required to have compressive strengths from 2500 PSI to 3500 PSI, depending on the exact application. A 5000 PSI concrete structure is considered to be a very high strength structural application.
